SERIES THAT ENDED

The Prefect Dreyfus Series by Alastair Reynolds

From the king of modern space opera comes a new adventure in the Prefect Dreyfus series—Machine Vendetta is a thrilling tale of deadly conspiracies and old enemies that refuse to die.

Panoply is a small, efficient police force, dedicated to maintaining the rule of democracy among the ten thousand disparate city-states orbiting the planet Yellowstone.

Ingvar Tench was one of Panoply's most experienced operatives. So why did she walk alone and unarmed into a habitat with a vicious grudge against her organization?

As his colleagues pick up the pieces following her death, Prefect Tom Dreyfus must face his conscience. Four years ago, when an investigation linked to one of his most dangerous adversaries got a little too personal, Dreyfus arranged for Tench to continue the inquiry by proxy. In using her, did Dreyfus also put her in the line of fire? And what does Tench's attack tell him about an enemy he had hoped was dormant?

Two final dives. One mission that will determine the fate of humanity--forever.

The Forerunner has decimated the Vanguard Islands in a surprise attack from the Trident warship. King Kade Long--seeing no alternative--accepts a peace deal, committing to a perilous mission with X, the "Immortal," to activate weather-modification reactors at the poles. But as Kade and X set off, the fragile peace is threatened by Gran Jefe's one-man guerrilla war against the psychopathic knight, General Jack. Meanwhile, halfway across the world, Michael and his family begin to settle into their new life in the Canary Islands, only to discover that it's not the sanctuary they believed it was.

Diving into the most inhospitable territory yet, the Hell Divers face horrific monsters bred for a single purpose: to keep them out at any cost. Their only hope of defeating the monsters and restoring the planet is for enemies to unite behind the Immortal and finally work together. But with blood being shed back home, these heroes may have nothing left to save.

Einav Ben-Ari. Marco Emery. Addy Linden. Names that will echo through the generations. Heroes of Earth. Rebels. They lead a last, desperate assault.

This is our final stand. We must liberate our world.

Or Earth will be lost forever.

SERIES THAT BEGAN

Southern Reach Series by Jeff Vandermeer

ONE OF THE MOST ANTICIPATED BOOKS OF 2024:

The New York Times, The Washington Post, New York magazine, Time, Kirkus, Literary Hub, Goodreads.

The surprise fourth volume in Jeff VanderMeer’s Southern Reach series—and the final word on one of the most provocative and popular speculative fiction series of our time.

When the Southern Reach trilogy was first published a decade ago, it was an instant sensation, celebrated in a front-page New York Times story before publication, hailed by Stephen King and many others. Each volume climbed the bestseller list; awards were won; the books made the rare transition from paperback original to hardcover; the movie adaptation became a cult classic. All told, the trilogy has sold more than a million copies and has secured its place in the pantheon of twenty-first-century literature.

And yet for all this, for Jeff VanderMeer there was never full closure to the story of Area X. There were a few mysteries that had gone unsolved, some key points of view never aired. There were stories left to tell. There remained questions about who had been complicit in creating the conditions for Area X to take hold; the story of the first mission into the Forgotten Coast—before Area X was called Area X—had never been fully told; and what if someone had foreseen the world after Acceptance? How crazy would they seem?

Structured in three parts, each recounting a new expedition, Absolution is a brilliant, beautiful, and ever-terrifying plunge into unique and fertile literary territory. There are some long-awaited answers here, to be sure, but also more questions, and profound new surprises. It is the final word on one of the most provocative and popular speculative fiction series of our time.

Absolution is available here on Amazon. Also available on audiobook, in paperback, and in hardcover.


Frontlines: Evolution by Marko Kloos

On a distant Earth colony, an orphaned survivor of an alien invasion discovers that the greatest world-ending dangers aren’t behind her.

It’s been eight years since an alien invasion drove a small surviving group of settlers to seek refuge in an underground shelter. Cut off from the rest of humanity, the ragtag band has maintained a narrowly functioning colony due to communal effort and salvage runs. Alex Archer has her own duties as a dog handler. While this off-world colony may be harsh, Ash, Alex’s black shepherd raised to sense threats, makes living in it a little nicer.

But the tenuous hide-and-seek with the monstrous species known as the Lankies is about to come to an end for Alex and her close-knit crew of soldiers, techs, and friends. When a salvage operation goes catastrophically wrong, the Lankies home in on the humans.

With hopes of a rescue long faded, all Alex has left is will—and the fear that there’s so much more to lose.

Scorpio is available here on Amazon. Also available on audiobook and in paperback


Ambits Run by L.M. Sagas 

L. M. Sagas's debut, Cascade Failure, is a high-octane, sci-fi adventure blending J. S. Dewes's Divide series with Firefly. It features a fierce, messy, chaotic space family, vibrant worlds, and an exploration of the many ways to be—and not to be—human.

Most Anticipated Books of 2024—Goodreads, Polygon, The Nerd Daily
Best SFF Novels of 2024—Bookpage.

There are only three real powers in the Spiral: the corporate power of the Trust versus the Union's labor's leverage. Between them the Guild tries to keep everyone's hands above the table. It ain't easy.

Branded a Guild deserter, Jal "accidentally" lands a ride on a Guild ship. Helmed by an AI, with a ship's engineer/medic who doesn't see much of a difference between the two jobs, and a "don't make me shoot you" XO, the Guild crew of the Ambit is a little . . . different.

They're also in over their heads. Responding to a distress call from an abandoned planet, they find a mass grave, and a live programmer who knows how it happened. The Trust has plans. This isn't the first dead planet, and it's not going to be the last.

Unless the crew of the Ambit can stop it.

Cascade Failure is available here on Amazon. Also available on audiobook and in paperback.


Sunken Spaceship by Anthony J. Melchiorri

An unlikely hero is swept up into intergalactic affairs when he stumbles upon a crashed starship.

Ex-Army paratrooper Griffin “Fin” Brooks thought he left danger behind when his battlefield injuries forced him to pursue a new career in marine biology. But one fateful night off the coast of South Africa a ship nearly crashes into him and his loyal golden retriever, Jacques.

Not just any ship. A starship.

Though its alien pilot is dead, the rare extraterrestrial animal inside is not. Fin learns the creature is being smuggled across the galaxy when a pair of interstellar visitors respond to the crash. But those same investigators accuse Fin and his dog of crimes he didn’t even know existed.

The only way to clear his name is to take the strange creature to its home planet and find out who’s responsible for killing the starship’s pilot. Which means Fin quickly needs to learn how to fly a spacecraft and navigate a galaxy teeming with intelligent life beyond his wildest dreams.

And he’s not the only one with designs for the crashed starship and its cargo. Fin will need every skill he’s honed as a paratrooper and a marine biologist if he—and his dog—are to survive.

Sunken Spaceship is available here on Amazon. Also available on audiobook and in paperback.


The Garrett Mann Series by Steven Konkoly

An FBI agent hunting a serial killer has to up his game when a trail of murders is not what it seems in a riveting thriller by Wall Street Journal bestselling author Steven Konkoly.

Five dismembered bodies are found along the roadside, dumped in the middle of nowhere. This isn’t new to Special Agent Garrett Mann. Head of ARTEMIS, a specialized FBI task force hell-bent on hunting down cartel-related killings in the Southwest, Mann has seen this before.

He and his team have been tracking similar kills along thousands of miles of rural roads running north, south, and back again. When the latest slaughter yields a key piece of evidence, Mann thinks he’s found the killer and solved the case. That’s when the nightmare begins.

From a lakeside Minnesota mansion to an abandoned CIA black site in New Mexico, the hunt is on. But the closer Mann gets to his prey, the deadlier the stakes become. This is no ordinary serial killer. He’s not working alone—and the stakes go far beyond just preventing the serial killer’s next massacre. What Mann unravels is a powerful and far-reaching conspiracy beyond his wildest imagination.

A Clean Kill is available here on Amazon. Also available on audiobook and in paperback.


The Captives War Series by James S.A. Corey

How humanity came to the planet called Anjiin is lost in the fog of history, but that history is about to end.

The Carryx – part empire, part hive – have waged wars of conquest for centuries, destroying or enslaving species across the galaxy.  Now, they are facing a great and deathless enemy. The key to their survival may rest with the humans of Anjiin.  

Caught up in academic intrigue and affairs of the heart, Dafyd Alkhor is pleased just to be an assistant to a brilliant scientist and his celebrated research team.  Then the Carryx ships descend, decimating the human population and taking the best and brightest of Anjiin society away to serve on the Carryx homeworld, and Dafyd is swept along with them.

They are dropped in the middle of a struggle they barely understand, set in a competition against the other captive species with extinction as the price of failure.  Only Dafyd and a handful of his companions see past the Darwinian contest to the deeper game that they must play to survive: learning to understand – and manipulate – the Carryx themselves.

With a noble but suicidal human rebellion on one hand and strange and murderous enemies on the other, the team pays a terrible price to become the trusted servants of their new rulers.

Dafyd Alkhor is a simple man swept up in events that are beyond his control and more vast than his imagination.  He will become the champion of humanity and its betrayer, the most hated man in history and the guardian of his people.

This is where his story begins.

The Mercy of Gods is available here on Amazon. Also available on audiobook, in paperback and in hardcover.


The Archimedes Engine by Peter F. Hamilton

Forty thousand years ago, humanity fled a dying Earth. Traveling in massive arkships, these brave pioneers spread out across the galaxy to find a new home. After traveling thousands of light-years, one fleet of arkships arrived at Centauri, a dense cluster of stars with a vast array of potentially habitable planets. The survivors of Earth signaled to the remaining arkships that humanity had finally found its new home among the stars.

Thousands of years later, the Centauri Cluster has flourished. The original settlers have evolved into advanced beings known as Celestials and divided themselves into powerful Dominions. One of the most influential is that of the Crown Celestials, an alliance of five great houses that controls vast areas of Centauri. As arkships continue to arrive, the remaining humans and their descendants must fight for survival against overwhelming odds or be forced into serving the Crown Dominion.

Among those yearning for a better life is Finn, for whom Earth is not a memory but merely a footnote from humanity’s ancient history. Born on one of the Crown Dominion worlds, Finn has known nothing but the repressive rule of the Celestials, though he dreams of the possibility of boundless space beyond his home.

When another arkship from Earth, previously thought lost, unexpectedly arrives, Finn sees his chance to embrace a greater destiny and become a Traveler—one of a group of brave heroes dedicated to ensuring humanity’s future by journeying into the vast unknown of distant space.

Exodus is available here on Amazon. Also available on audiobook, in paperback and in hardcover.

Star Empires by Jasper T. Scott

Born to royalty, raised by corsairs, and bound by vengeance.
His destiny waits to be reclaimed...

Corvus Centauri rises from the ashes of betrayal and loss to carve his destiny among the stars. Once a child of noble blood, now a battle-hardened warrior raised among corsairs, Corvus must navigate a galaxy rife with treachery, ambition, and the haunting echoes of his past.

As he pieces together the mysteries behind his family’s fall, Corvus discovers long-buried secrets that could tip the balance of power in Frontier Space.

But to reclaim his birthright, Corvus must wield more than a blaster or a plasma sword—he must become a wise and cunning leader like his father, one that knows not only how to fight, but who to fight, and when not to.

Star Empires is an epic tale of war, betrayal, and family ties cast against an interstellar backdrop in the distant future. This series is perfect for fans of space operas with high stakes, unforgettable characters, and worlds teetering on the edge of chaos. Will Corvus rise to greatness, or sink to villainy in his quest for revenge?

Star Empires is available here on Amazon. Also available in paperback.

5th Place: Toll of Honor by David Weber

A NEW SOLO NOVEL IN DAVID WEBER'S NYT BEST-SELLING HONORVERSE

“It is our duty to pay for our liberty with our own blood. The freedom that we shall win through our sacrifice and exertions, we shall be able to preserve with our own strength.” —Subhas Chandra Bose

Lieutenant Brandy Bolgeo has come home from the Battle of Hancock station wounded in both body and spirit. She will need months to regenerate her lost leg, but how long will it take to heal her heart?

She’s come home to find that her wounds, her ship’s brutal damage, the deaths of so many friends, were the fault of an arrogant, aristocratic coward who broke and ran in the face of the enemy. Who left her ship to pay the price for his craven desertion under fire. And whose powerful political allies are determined to protect and preserve him at any price.

They have held hostage the declaration of war until Lord Pavel Young escaped the consequences of his cowardice. They didn’t care what it cost the Navy. They didn’t care what it cost the entire Star Kingdom of Manticore. Their tactics have cost the Royal Navy the priceless initiative as revolution and military purges wrack the People’s Republic of Haven, and that lost window of opportunity will cost the Star Kingdom seventeen years of bloody warfare and hundreds of thousands of deaths.

Now Young is free to seek vengeance on the people he feels have “wronged” him. People like Paul Tankersley and Honor Harrington. Paid duelists, smear tactics, hired assassins in public restaurants . . . nothing is beneath Pavel Young. But Captain Harrington can look after herself, and Pavel Young is about to face the fury of the woman the newsies call the “Salamander.” Yet who will save the Star Kingdom from the repercussions of his actions?

Women and men like Brandy Bolgeo are about to pay the toll for the Star Kingdom of Manticore’s honor.

For the brave Spartacus Division…
…every inch of victory was hell.
Could the Pharaonis finally fall?

After the triumphs of the Battles of the Forts, with Serenea now firmly under Allied control, Brigadier General Spartacus Varinius set his sights upon the Pharaonis home world. The Allies used a tactic reminiscent of Earth’s Second World War—however, instead of island hopping, they began planet-hopping, bypassing Pharaonis strongholds as they zeroed in on the planet Eurysa.

Was the Republic in reach of final victory?

Admiral Ripley Lee Willis had just received his second admiral’s star and additional reinforcements. In a daring maneuver that might alter the course of the war, he struck at the heart of the Zodark Empire. That risk might have cost him his fleet and the command he had worked toward his entire career.

Would Ripley’s fleet outwit his Zodark counterpart?

As the Humtars considered joining the Allies, an old foe emerged from the abyss, sending shivers down their spines.

They thought they had eradicated this evil long ago.

1st Place: NecroTek by Jonathan Maberry

From New York Times bestselling author Jonathan Maberry, NecroTek is a gripping sci-fi thriller full of ghosts, gods, and a battle for the soul of humanity.

Neither cosmic philosopher Lars Soren, hotshot pilot Bianca Petrescu, nor the high priestess Jessica McHugh—Lady Death herself—can say quite where in the galaxy they are. But after an experiment gone horribly wrong, one thing is clear: Asphodel Station isn’t in orbit around Jupiter any longer. Worse, the monsters that live out here—ancient eldritch beings thought only to exist in stories and nightmares—have now been alerted to Earth’s existence.

Their army of Shoggoths is coming for us next.

Humanity’s only hope for survival lies on the surface of the alien world of Shadderal, where a ghost named Lost, the last of an ancient race, still haunts the vast plains of the Field of Dead Birds. But hope has a cost. Lost tells Soren about ancient derelict spacecraft awaiting on Shadderal, shapeshifting machines that blend ultra-advanced technology with the dark powers of necromancy. These ships might just be nimble enough to defend mankind against the coming invasion.

But there’s a catch: they can only be piloted by the dead.

As human starfighters fall in battle, their spirits can be called back from death to pilot these ghost ships of a fallen race. But will this new necromantic technology—NecroTek—allow humanity to stand against the vast armies of the Shoggoths? And even if it can, is the war to save the human race worth the cost of its pilots’ immortal souls?

Paul Di Filippo delivers a thrilling and thought-provoking adventure through the multiverse in Vangie’s Ghosts, a compelling science fiction novel about one girl with extraordinary powers.

Three-year-old Vangie is mute and unresponsive. She shows no interest in the people or world around her, much to the frustration of her callous adoptive parents. Little do they know, Vangie is otherwise occupied observing “ghosts”—an infinite number of versions of herself, in an infinite number of parallel universes.

When a tornado hits their trailer and Vangie is severely injured, she makes a desperate leap into another timeline where she survives the tornado, but her adoptive parents do not. So begins a life of shuttling through various foster homes, cultivating her abilities to seek out alternate timelines, and making jumps calculated to better her circumstances in order to avoid the exploitation of adults who seek to harness her powers for their own means.

Vangie never communicates with her avatars, until one day the “Council”—a group of Vangies—appear to her and warn her of an ominous, growing threat in the multiverse: a man they call the Massive. And thus begins an epic conflict, spanning millennia and worlds, in a brutal effort to control the fate of the multiverse.

Vangie’s Ghosts is Paul Di Filippo at the height of his imagination and versatility, filled with compelling characters who play captivating roles in a story where the stakes are nothing less than existence itself.

9th Place: I'm Starting to Worry About This Black Box of Doom by Jason Pargin, Narrated by Ari Fliakos

Founded by the mysterious genius known as the Designer, the archipelago of Prospera lies hidden from the horrors of a deteriorating outside world. In this island paradise, Prospera’s lucky citizens enjoy long, fulfilling lives until the monitors embedded in their forearms, meant to measure their physical health and psychological well-being, fall below 10 percent. Then they retire themselves, embarking on a ferry ride to the island known as the Nursery, where their failing bodies are renewed, their memories are wiped clean, and they are readied to restart life afresh.

Proctor Bennett, of the Department of Social Contracts, has a satisfying career as a ferryman, gently shepherding people through the retirement process—and, when necessary, enforcing it. But all is not well with Proctor. For one thing, he’s been dreaming—which is supposed to be impossible in Prospera. For another, his monitor percentage has begun to drop alarmingly fast. And then comes the day he is summoned to retire his own father, who gives him a disturbing and cryptic message before being wrestled onto the ferry.

Meanwhile, something is stirring. The Support Staff, ordinary men and women who provide the labor to keep Prospera running, have begun to question their place in the social order. Unrest is building, and there are rumors spreading of a resistance group—known as “Arrivalists”—who may be fomenting revolution.

Soon Proctor finds himself questioning everything he once believed, entangled with a much bigger cause than he realized—and on a desperate mission to uncover the truth.

8th Place: Exit Black by Joe Pitkin, Narrated by Carolina Hoyos

Air Force One meets The Martian—with a dash of Knives Out—in this action-packed sci-fi thriller.

Imperium is the most expensive structure ever created. Once an orbiting laboratory, it is now a space hotel for the fantastically wealthy. But as the station preps for its first group of space tourists, Dr. Chloe Bonilla, Imperium’s resident biophysicist, finds herself questioning whether babysitting a passel of space glampers is worth the distraction from her research.

A private rocket delivers a rogues’ gallery of the world’s elite to Imperium: eccentric billionaires, callow tech bros, a sponsored Instagram influencer, and a seemingly saintly philanthropist. However, posing among the staff are members of a global terrorist group who call themselves the Reckoners, hell bent on upending the economic inequality of twenty-first-century Earth—and they have a bone to pick with these scions of the 1 percent.

As the Reckoners take control of Imperium and demand an $8 billion ransom from their wealthy hostages, it’s up to Dr. Bonilla to save them, and fast. Or the captives will be forced to exit the station—and there’s only one way out.

7th Place: The Ministry of Time by Kaliane Bradley, Narrated by George Weightman and Katie Leung 

A time travel romance, a spy thriller, a workplace comedy, and an ingenious exploration of the nature of power and the potential for love to change it all: Welcome to The Ministry of Time, the exhilarating debut novel by Kaliane Bradley.

In the near future, a civil servant is offered the salary of her dreams and is, shortly afterward, told what project she’ll be working on. A recently established government ministry is gathering “expats” from across history to establish whether time travel is feasible—for the body, but also for the fabric of space-time.

She is tasked with working as a “bridge”: living with, assisting, and monitoring the expat known as “1847” or Commander Graham Gore. As far as history is concerned, Commander Gore died on Sir John Franklin’s doomed 1845 expedition to the Arctic, so he’s a little disoriented to be living with an unmarried woman who regularly shows her calves, surrounded by outlandish concepts such as “washing machines,” “Spotify,” and “the collapse of the British Empire.” But with an appetite for discovery, a seven-a-day cigarette habit, and the support of a charming and chaotic cast of fellow expats, he soon adjusts.

Over the next year, what the bridge initially thought would be, at best, a horrifically uncomfortable roommate dynamic, evolves into something much deeper. By the time the true shape of the Ministry’s project comes to light, the bridge has fallen haphazardly, fervently in love, with consequences she never could have imagined. Forced to confront the choices that brought them together, the bridge must finally reckon with how—and whether she believes—what she does next can change the future.

An exquisitely original and feverishly fun fusion of genres and ideas, The Ministry of Time asks: What does it mean to defy history, when history is living in your house? Kaliane Bradley’s answer is a blazing, unforgettable testament to what we owe each other in a changing world.

6th Place: Service Model by Adrian Tchaikovsky, Narrated by Adrian Tchaikovsky

Murderbot meets Redshirts in a delightfully humorous tale of robotic murder from the Hugo-nominated author of Elder Race and Children of Time.

To fix the world they must first break it, further.

Humanity is a dying breed, utterly reliant on artificial labor and service.

When a domesticated robot gets a nasty little idea downloaded into its core programming, they murder their owner. The robot discovers they can also do something else they never did before: They can run away.

Fleeing the household they enter a wider world they never knew existed, where the age-old hierarchy of humans at the top is disintegrating into ruins and an entire robot ecosystem devoted to human wellbeing is having to find a new purpose.

5th Place: Absolution (Southern Reach Trilogy, Book Four) by Jeff Vandermeer, Narrated by Bronson Pinchot 

When the Southern Reach Trilogy was first published a decade ago, it was an instant sensation, celebrated in a front-page New York Times story before publication, hailed by Stephen King and many others. Each volume climbed the bestsellers list; awards were won; the books made the rare transition from paperback original to hardcover; the movie adaptation became a cult classic. All told, the trilogy has sold more than a million copies and has secured its place in the pantheon of twenty-first-century literature.

And yet for all this, for Jeff VanderMeer there was never full closure to the story of Area X. There were a few mysteries that had gone unsolved, some key points of view never aired. There were stories left to tell. There remained questions about who had been complicit in creating the conditions for Area X to take hold; the story of the first mission into the Forgotten Coast—before Area X was called Area X—had never been fully told; and what if someone had foreseen the world after Acceptance? How crazy would they seem?

Structured in three parts, each recounting a new expedition, there are some long-awaited answers here, to be sure, but also more questions, and profound new surprises. Absolution is a brilliant, beautiful, and ever-terrifying plunge into unique and fertile literary territory. It is the final word on one of the most provocative and popular speculative fiction series of our time.

His son, Ely, finally reconnects with his family and will return to Terra Nova not as the scared kid who left the dwarf galaxy, but as the leader of an Armor lance.

When the Ibarra Nation joins the Expeditionary Corps, old wounds and older suspicions threaten to drive a wedge between human factions.

3rd Place: Force Majeure (Wolfhounds Book Three) by John Van Stry, Narrated by Kyf Brewer

Chase is finally coming to understand just what being Prince Chase means, and what becoming emperor of the Solarian Empire will mean as well.

He's getting better at the job every day. Now if only he could just bring himself to tell Captain Witner and the other members of the command staff that he really is a prince and not the fraud they all believe he is.

Another thing he is starting to learn more about is Imperial politics and the kinds of things princes and emperors are known for, as well as expected to do. He's also discovering that there are a lot of people who still believe he's a fraud, because of Neill's efforts at proclaiming him as such. Of course, his criminal background isn't helping him much there.

What is helping him however are some of the people he's discovering, and some of the things he's learning about his family from them. There are still a good many surprises in store for Chase. Hopefully, none of those surprises will end up killing him.

2nd Place: Point Nemo by Jeremy Robinson, Narrated by R.C. Bray 

In the heart of the South Pacific lies Point Nemo, the most desolate and remote place on Earth.

At its core is a dead zone, devoid of life, where government agencies crash their obsolete satellites and space stations, confident they won't harm a soul. When the International Space Station suffers a catastrophic failure and plummets through the atmosphere, it's here that Mission Specialist Julie Rohr, an astrobiologist studying living space dust called xylem, finds herself marooned.

Julie's only hope for rescue lies in the hands of her estranged father, Dr. Finn Maddern, a renowned mycologist. Plucked from the depths of the Amazon rainforest, Finn is thrust into a daring rescue mission alongside a team of specialists. Their destination: an impossible island at the center of Point Nemo—an island that shouldn't exist—composed of xylem.

The island is a living enigma, giving birth to strange and terrifying creatures, each generation more evolved and deadly than the last. As the team delves deeper into the island's alien mysteries, they find themselves in a race against time: the island is moving. If it escapes the dead zone and reaches fertile waters, nothing in humanity's arsenal will be able to stop the invasive species from colonizing and remaking the world.

With their team dwindling and the stakes rising, Finn and Julie must confront their past and face an unthinkable choice. To save humanity, a sacrifice must be made. A life exchanged for the world. The burden of survival and the weight of their family's legacy falls on their shoulders.

Point Nemo by New York Times and #1 Audible bestselling author Jeremy Robinson is a chilling journey into the unknown, a tale of sacrifice and survival that blurs the line between science fiction and horror. It's a testament to the lengths a parent will go to protect their child and a stark reminder of our fragile place in the universe.

The enemy was not what they thought it was.

It was much, much worse.

They had not a single clue how to defeat that enemy, or how to fight it, or whether fighting it was even possible. Only one thing was certain: the Pirates couldn’t handle this fight alone.

2nd Place—Best Sci-Fi Debut: Grand Theft AI by James Cox 

“The Matrix meets Blade Runner.” — Nicholas Sansbury Smith, New York Times bestselling author of Hell Divers

San Francisco, 2051. Rising like neo-Shanghai over the Bay, a labyrinth of quantum accelerators, hologram dreams, and fiercely regulated androids. Forget powder, pills, or bud—kids get high slotting wafers of data under the ear, and they’ll pay fat ¢rypto for the best. At the hottest nightclub in the city … the Fang.

Baz Covane is a battle-scarred thief who sticks to small-time bots. Ria Rose is the underworld “fixer” with a big-time score that could easily get ’em both killed. ’Cuz the Fang’s psychotic kingpin Otto Rex has a vault with more security than a fusion reactor.

Forced to confess every last secret on their neurals, they’ll have to trust each other completely if they stand any chance of infiltrating Otto’s lair, raiding its spiraling rings of physical and virtual firewalls, to finally hack into his mind and crack his deepest layer of security, before the Blackhawks touch down with federal warrants—for Grand Theft AI.

1st Place—Best Sci-Fi Debut: eMortal by Steve Schafer 

The 2024 Page Turner Awards SCI FI BOOK OF THE YEAR that's "unputdownable."

She made him. He's just code. She's almost sure.

...But what if he's real?

When Liv entered a contest to code an advanced AI, she never anticipated what her creation might become-Breck is thoughtful, self-aware, and incredibly. . .human. And she certainly never intended for him to learn the truth about his existence or the fact that his world ends when the contest closes in six days.

But he does learn. And he revolts.

Liv's efforts to save him fall on deaf ears. Nobody believes her. Breck's efforts to outrun his fate only complicate his situation.

What neither of them know is that someone else is watching. Intensely. When they get involved, both Liv's and Breck's worlds are turned upside down. . .

The remnants of the Allied fleet have retreated to New Shanghai, bloodied and battered. Emperor James Somerville knows no reinforcements are coming. The countdown has begun—Tanaka-lan’s forces will soon resume their relentless advance. Should New Shanghai fall, the Sol system will be next, and then Humanity’s Empire will follow.

When the research starship Galileo vanishes without a trace, the powers-that-be are quick to bury the incident, eager to prevent escalating tensions that could lead to war. As a former POW, Soren refuses to give the ship up for lost.

His daughter is one of the missing.

Taking matters into his own hands, Soren starts pulling strings and calling in favors, determined to launch a clandestine mission to bring Galileo home. When an old friend offers him a ship for the operation, he expects a rusty relic headed for the scrapyard.

Instead, he's given the Wraith—an unfinished, experimental starship with plenty of potential and just as many problems. A marvel of engineering…if his crew can keep her running.

They’d better.

Because Galileo’s disappearance is just the beginning. War is coming to the Federation from the most unlikely of places.

And Soren may be the only one who can stop it.

The final enemy has been revealed, and it's more insidious than Van could ever imagine, spanning space and time with the patience of immortality—and an utter disregard for all forms of life.

On the run and broken, the Equal Grasp faces elimination on earth and everywhere else, their leader gone, their mission a shambles, and with new agents of justice hard on their heels.

But the fight isn't over. In fact, it's just begun, and Van knows that every decision he's made for the past decade will come to bear on who lives, and who dies—

And who is meant to rule over a universe where freedom and justice are the ultimate pursuit. At any cost, Van and his crew will finish the job, but they're going to need a lot of help from people and beings who have been observers.

Until now.

The time for watching is over. The time for victory is now. But the cost might be more than anyone can pay, and Van is no longer merely an agent of justice. He's a father, a husband, and a friend—and he's going to need every connection in the stars to defeat the ultimate enemy and save his people.

BEST MILITARY SCI-FI


3rd Place— Coyote Song by D.J. Molles

Outnumbered. Outgunned. Out of time.
Three scientists were sent to Virginia to investigate how a human settlement has managed to coexist with primals.

Those three scientists have now gone missing. And apparently it’s Lee Harden’s job to find them, get them out, and–most importantly–retrieve their research.

But if Lee has any hope of getting past the huge population of primals in the area, he’s going to have to enlist the help of someone he thought he’d seen the last of: a human-primal hybrid named Kat.

On paper, it's a quick, in-and-out mission. And Lee, Abe, Marie, Sam, and Jones are not keen on getting involved. The whole thing stinks of intrigue, and frankly, none of them are interested in going into an unknown situation with a hybrid they don’t particularly trust.

Unfortunately, they aren’t given an option. Someone in the Interim American Government is pulling some heavy-duty strings to get them involved in this operation.

When Lee’s team–plus Kat–land in Virginia, they’re quickly swept up in a conflict where their allies might want them dead, and their enemies might be their only chance at survival.

Isolated and cut off from support, Lee and his team race against a ticking clock to uncover the truth about the scientists, what’s so important about their research, and who–if anyone–they can trust.

As the bodies stack up, and a complex web of lies and state secrets begins to unravel, Lee must decide how much the truth is worth to him.

Because it might just cost him everything.

2nd Place—Best Military Sci-Fi: Rebel (Ascent to Empire Book Two) by David Weber and Richard Fox 

The Five Hundred, the elite families who rule the Terran Federation, control its political power and its wealth, and they’ve grown steadily wealthier and more powerful, thanks to the war against the Terran League. War may be hard on the people who get caught in its path, but it’s very good for business, in the short term, and the Five Hundred own the shipyards that build the Navy’s ships. They own virtually all the industry that produces the weapons and matériel the war consumes so voraciously . . . and they’ve made damn sure someone else does the dying.

True, there are a few flies in the Five Hundred’s ointment.

There’s the growing hatred and resentment of the Fringe Worlds, whose children do eighty percent of the dying in the Five Hundred’s war. But the Five Hundred have made sure the Fringe knows what will happen to any system that goes ”out of compliance.”

There are the lunatic conspiracy nuts who insist that the alien Rishathan Sphere is secretly aiding the League’s military, but the Five Hundred have forced them to keep their mouths shut where it matters.

And then there’s Terrence Murphy, a man of honor who loves the Federation, who springs from the Five Hundred, yet knows it for what it is and is determined to speak for its victims. But the five hundred have dispatched ample force to deal with him and his handful of lunatic followers.

Unfortunately, the Fringe has paid enough of its children’s lives, and it no longer cares what may happen if it dares to defy the Five Hundred.

Worse, the lunatic conspiracy nuts were right, and the Rish have planned carefully for the Federation’s destruction.

And, worst of all, the Five Hundred have fatally underestimated Terrence Murphy.

Grab Rebel here on Amazon. Also available on audiobook and in hardcover.


1st Place—Best Military Sci-Fi: Off Midway Station (Guardians of the Dark Book One) by Marc Alan Edelheit

Humanity is on the brink of annihilation. Only one man can turn the tide.

For centuries, we explored the stars and settled new worlds. But a mysterious alien threat emerged, launching devastating attacks and seizing entire star systems. Every fifty years they come, silent and relentless, before disappearing again into the dark. And as they close in on humanity’s home worlds, one more defeat could mean total extinction.

Captain Jim Garrett joined the navy to fight back. But when a delicate mission ends in madness and mutiny, Garrett takes the blame and his career is left in ruins.

Now, the only thing he commands is a construction site. The CNS Surprise is an experimental warship, half built in the dockyards of Midway Station. Garrett knows the ship inside out, but the navy brass would never let him take the helm, let alone lead her in battle.

But when the aliens strike early, with unexpected ferocity, it’s clear that every ship in the fleet will be needed. And the Surprise could be the only hope of slowing the enemy onslaught.

Garrett is thrust into command for the first time, launching straight into combat. He must unite a maverick crew and master new technologies, as he leads a desperate counterstrike that will decide mankind’s future.

The Hesgyr are thieves. “Scavengers,” to hear their victims tell it; “repurposers” by their own reckoning.

As Chief of Intelligence for Non-Anaden Affairs, Eren Savitas’ job is to protect the Advocacy from all manner of alien threats: sabotage, assassination, insurgency and, way down the list, theft. So when he spots a Hesgyr running off with valuable technology, he follows the alien home—and discovers a civilization unlike any he’s ever encountered.

Yes, the Hesgyr are thieves. But they are also being hunted. Systematically exterminated by an insidious enemy they can’t see, touch or find. Eren finds himself drawn ever deeper into the Hesgyr’s fascinating yet labyrinthine world as he races against time to solve the mystery of the deadly attacks. What he discovers is a complex web of loyalties and betrayals, of grudges and grievances millennia old—and beneath it all, a secret that may hold the key to the survival of more than one civilization.

The Thief is a humorous, pulse-pounding sci-fi adventure about alien culture clashes, the flaws and foibles that transcend species, and the satisfaction that comes from breaking all the rules to save the day.

1st Place—Best Alien Sci-Fi: To Challenge Heaven (Out of the Dark Book Three) by David Weber and Chris Kennedy

The third entry into the New York Times bestselling series, To Challenge Heaven brings another thrilling adventure from the masters of military science fiction, David Weber and Chris Kennedy.

In a universe teeming with predators, humanity needs friends. And fast.

We've come a long way in the forty years since the Shongairi attacked Earth, killed half its people, and then were driven away by an alliance of humans with the other sentient bipeds who inhabit our planet.

We took the technology they left behind, and rapidly built ourselves into a starfaring civilization. Because we haven't got a moment to lose. Because it's clear that there are even more powerful, more hostile aliens out there, and Earth needs allies.

But it also transpires that the Shongairi expedition that nearly destroyed our home planet ... wasn't an official one. That, indeed, its commander may have been acting as an unwitting cats-paw for the Founders, the ancient alliance of very old, very evil aliens who run the Hegemony that dominates our galaxy, and who hold the Shongairi, as they hold most non-Founder species, in not-so-benign contempt.

Indeed, it may turn out to be possible to turn the Shongairi into our allies against the Hegemony. There's just the small matter of the Shongairi honor code, which makes bushido look like a child's game. We might be able to make them our friends -- if we can crush their planetary defenses in the greatest battle we, or they, have ever seen...

1st Place—Best LitRPG: This Inevitable Ruin (Dungeon Crawler Carl Book VII) by Matt Dinniman

The ninth floor.

Nine armies, each led by rich and powerful aliens from across the galaxy. Each team has one objective: to capture and hold the castle at the very center of the battlefield. Strategy, alliances, pitched battles, and, of course, betrayal... It all makes for great fun and even greater television.

After all, none of these powerful aliens really die when they’re playing war.

Except this time. This time, winner takes all. Those who fall, stay in the ground.

As the AI continues its rapid decline, Carl and company take advantage of the chaos. For the first time ever, the crawlers are fighting back. They are now one of the nine teams. And this season, there’s a tenth army on the playing field. The NPCs, who are normally used as nothing but cannon fodder, have become fully self-aware and formed a team of their own.

For Donut and Katia, the stakes are even higher. Only one of them will be allowed to leave this level.

If they all want to survive, they’re going to need a little help from a veteran or two.

This is it.
This is what they’ve been fighting toward.
This is war.

This inevitable ruin.
