Questland by Carrie Vaughn 

Release Date: June 22nd, 2021

Literature professor Dr. Addie Cox is living a happy, if sheltered, life in her ivory tower when Harris Lang, the famously eccentric billionaire tech genius, offers her an unusual job. He wants her to guide a mercenary strike team sent to infiltrate his island retreat off the northwest coast of the United States. Addie is puzzled by her role on the mission until she understands what Lang has built:  Insula Mirabilis, an isolated resort where tourists will one day pay big bucks for a convincing, high-tech-powered fantasy-world experience, complete with dragons, unicorns, and, yes, magic.

Unfortunately, one of the island's employees has gone rogue and activated an invisible force shield that has cut off all outside communication. A Coast Guard cutter attempting to pass through the shield has been destroyed. Suspicion rests on Dominic Brand, the project’s head designer— and Addie Cox's ex-boyfriend. Lang has tasked Addie and the mercenary team with taking back control of the island at any cost.

But Addie is wrestling demons of her own—and not the fantastical kind. Now, she must navigate the deadly traps of Insula Mirabilis as well as her own past trauma. And no d20, however lucky, can help Addie make this saving throw.

His Scout Team had been burned, disavowed by his chain of command and the owner of the stolen ship he was flying was after them to get it back. To make matters even more complicated, the man Jacob had stolen the ship from is an infamous outlaw and mercenary named Jason Burke… his father.

Being hunted down by both the United Earth Navy and the mercenary group that called itself Omega Force, Jacob has only one chance to keep his team out of a military prison and bring down the head of the One World terrorist faction that always seemed to be three steps ahead of him… and that was only if his father didn't catch him first.

The 22 Murders of Madison May by Max Barry

Release Date: July 6th, 2021

"I love you. In every world."

Young real estate agent Madison May is shocked when a client at an open house says these words to her. The man, a stranger, seems to know far too much about her, and professes his love--shortly before he murders her.

Felicity Staples hates reporting on murders. As a journalist for a midsize New York City paper, she knows she must take on the assignment to research Madison May's shocking murder, but the crime seems random and the suspect is in the wind. That is, until Felicity spots the killer on the subway, right before he vanishes.

Soon, Felicity senses her entire universe has shifted. No one remembers Madison May, or Felicity's encounter with the mysterious man. And her cat is missing. Felicity realizes that in her pursuit of Madison's killer, she followed him into a different dimension--one where everything about her existence is slightly altered. At first, she is determined to return to the reality she knows, but when Madison May--in this world, a struggling actress--is murdered again, Felicity decides she must find the killer--and learns that she is not the only one hunting him.

Traveling through different realities, Felicity uncovers the opportunity--and danger--of living more than one life.

The Freedom will never surrender. The Freedom will never flee. The long, cold night has come to Earth, but the Freedom shines bright.

Release Date: July 13th, 2021

It's been centuries since the robots of Panga gained self-awareness and laid down their tools; centuries since they wandered, en masse, into the wilderness, never to be seen again; centuries since they faded into myth and urban legend.

One day, the life of a tea monk is upended by the arrival of a robot, there to honor the old promise of checking in. The robot cannot go back until the question of "what do people need?" is answered.

But the answer to that question depends on who you ask, and how.

They're going to need to ask it a lot.

Becky Chambers's new series asks: in a world where people have what they want, does having more matter?

Jamie, eager to do anything, immediately signs on.

What Tom doesn't tell Jamie is that the animals his team cares for are not here on Earth. Not our Earth, at least. In an alternate dimension, massive dinosaur-like creatures named Kaiju roam a warm, human-free world. They're the universe's largest and most dangerous panda and they're in trouble.

While some species succumb to the pandemonium, the Chut'un forge an unholy symbiotic relationship—The Order—with red Europhids, a vast hive intelligence populating the universe's far reaches. Desiring structure and fearing the unknown, they cull everything opposed to their plan, including the Europhids' blue counterparts, carrying out a galactic genocide until only one blue Europhid remains...inside Moses Montgomery, aka 'Dark Horse.'

As a Rapid Reaction Force Marine from 1989, Dark Horse and his team were sent 1000 years into the future where they defeated the Union, an evil fascist empire. Back in the present, after preventing the Union from ever forming, Dark Horse and his team of...unique operators from the past and the future are ready to kick back, listen to some tunes, and enjoy the timeline they saved.

But as the last threat to The Order's machinations, Dark Horse finds himself with an alien target on his back. Joined by Dan Delgado and Wini Finch (The Others), and Owen McCoy (Flux), the team attempts to understand the gates that first appeared in New Hampshire, and now in Antarctica. Despite their vast experience with the strange and otherworldly, none of them are prepared for what comes next. Three members of the team are abducted, whisked away to another planet. Alive or dead, no one knows.

Dark Horse and his now rag-tag team struggle to track down their missing teammates while being hunted themselves. With the fate of his friends—and all of Earth—hanging in the balance, Dark Horse is forced to take insane risks, create chaos, and do anything to get his people back.

Mesme has long been meddling with the fate of the universe, but the events in the Oneiroi Nebula have exposed its deceptions. A schism erupts between Alex and Mesme over the secrets the Katasketousya keeps—and if their relationship isn’t mended, the world may lose its best chance at salvation.

The fractures threatening Concord’s survival aren’t merely personal, and the ramifications of the Ruda’s betrayal in the last battle prove costly to everyone. The Rasu begin deploying antimatter weapons, thereby neutralizing Concord’s greatest advantage, its impervious adiamene warships. Now losing ships, people and planets as the Rasu close in on the Milky Way, Miriam Solovy finds herself short on options and out of time.

But Alex has never let those kind of odds stop her, and so a desperate plan is hatched—one that will either save civilization, or doom it to annihilation.

In Amaranthe, where exotic alien life, AIs, wormholes, indestructible starships and the promise of immortality rule the day, no feat seems out of reach for humanity. But when the worlds of Aurora Rhapsody and Asterion Noir collide and the Rasu horde descends upon them both, more will be asked of heroes past and future. More will be given and more taken, and when the dust settles the very fabric of Amaranthe will be altered forever.

“It is pointless to worry about the possible malevolent intentions of an advanced civilization with whom we might make contact. It is more likely that the mere fact they have survived so long means they have learned to live with themselves and others.” ―Carl Sagan, Cosmos

It may be pointless to worry, but it sure is fun to imagine! Or rather, it's fun to get caught up in the imaginings of our favorite sci-fi authors. Curious to see which imagined first contact scenario the Discover Sci-Fi community loved best? Read on to find out!

Here, without further ado, based on the combined nominations and votes here on the Discover Sci-Fi blog and in the Facebook group, are the top 10 first contact books of all-time! 

10. Live Free or Die by John Ringo

First Contact Was Friendly.

When aliens trundled a gate to other worlds into the solar system, the world reacted with awe, hope and fear. But the first aliens to come through, the Glatun, were peaceful traders and the world breathed a sigh of relief.

Who Controls the Orbitals, Controls the World.

When the Horvath came through, they announced their ownership by dropping rocks on three cities and gutting them. Since then, they've held Terra as their own personal fiefdom. With their control of the orbitals, there's no way to win and earth's governments have accepted the status quo.

6. Expeditionary Force by Craig Alanson

We were fighting on the wrong side, of a war we couldn't win. And that was the good news.

The Ruhar hit us on Columbus Day. There we were, innocently drifting along the cosmos on our little blue marble, like the native Americans in 1492. Over the horizon come ships of a technologically advanced, aggressive culture, and BAM! There go the good old days, when humans only got killed by each other. So, Columbus Day. It fits.

4. Childhood's End by Arthur C. Clarke

In the near future, enormous silver spaceships appear without warning over mankind’s largest cities. They belong to the Overlords, an alien race far superior to humanity in technological development. Their purpose is to dominate Earth. Their demands, however, are surprisingly benevolent: end war, poverty, and cruelty. Their presence, rather than signaling the end of humanity, ushers in a golden age . . . or so it seems.

Without conflict, human culture and progress stagnate. As the years pass, it becomes clear that the Overlords have a hidden agenda for the evolution of the human race that may not be as benevolent as it seems.

3. The War of the Worlds by H.G. Wells

The War of the Worlds (1898), by H. G. Wells, is an early science fiction novel which describes an invasion of England by aliens from Mars. It is one of the earliest and best-known depictions of an alien invasion of Earth, and has influenced many others, as well as spawning several films, radio dramas, comic book adaptations, and a television series based on the story. The 1938 radio broadcast caused public outcry against the episode, as many listeners believed that an actual Martian invasion was in progress, a notable example of mass hysteria.

2. Rendezvous With Rama by Arthur C. Clarke

An enormous cylindrical object has entered Earth’s solar system on a collision course with the sun. A team of astronauts are sent to explore the mysterious craft, which the denizens of the solar system name Rama. What they find is astonishing evidence of a civilization far more advanced than ours. They find an interior stretching over fifty kilometers; a forbidding cylindrical sea; mysterious and inaccessible buildings; and strange machine-animal hybrids, or “biots,” that inhabit the ship. But what they don’t find is an alien presence. So who—and where—are the Ramans?

Often listed as one of Clarke’s finest novels, Rendezvous with Rama won numerous awards, including the Hugo, the Nebula, the Jupiter, and the British Science Fiction Awards. A fast-paced and compelling story of an enigmatic encounter with alien technology, Rendezvous with Rama offers both answers and unsolved mysteries that will continue to fascinate readers for generations.

"Just about every collaboration I've done has been done because I believed that the final product would be stronger in some ways than either of us would have produced on his or her own. The fact that the final book will be stronger in some ways doesn't necessarily mean that I expect it to be stronger in all ways, but it does mean that my collaborator and I are each going to be bringing different strengths to the table with us." —David Weber

It’s always fascinating to get a glimpse inside an author's writing process, be it solo or collaborative, and these words from Weber confirm that the best collaborative writers are choosing a collaborative path because they believe—for a variety of reasons—that, for some stories, it’s the way toward a stronger book.

The books in this week’s top 10 list are an indication of success in that aim, the two selections co-written by Weber included. Curious to see how each of these 10 co-written books ranked? Read on to see and let us know if you agree! 

Without further ado, based on the combined nominations and votes here on the Discover Sci-Fi blog and the Facebook group, here are the top 10 co-written sci-fi books of all time! 

10. Ruins of the Galaxy by J.N. Chaney and Christopher Hopper

“Absolutely masterful storytelling cadence that you two gentlemen have learned how to write and play off of each others style... It has been rare that I have enjoyed a book as immensely as I did this one.” —Eugene Hunter

Whether it’s the nominated series, Ruins of the Galaxy, or Ruins of the Earth, or Resonant Son, Eugene Hunter’s words ring true: Chaney and Hopper do an incredible job of playing off each one another, each of their strengths as writers and storytellers shining though. If you haven’t read anything by this duo, Ruins of the Galaxy is a really great place to jump in. 

The mission is simple. Escort an emissary to an intergalactic peace summit. Try not to get in the way. But when an explosion rocks the tower and sends everyone into a panic, Magnus and his asset find themselves cut off from the rest of the team.

Worse still, a dying alien chieftain gives them a priceless drive of intel, marking them for death.

The mission has officially changed.

With enemies on all sides, Magnus must do everything in his power to protect the emissary and escape the tower. There is no back up. There is no chance for failure.

The fate of the entire galaxy now lies in the hands of a Republic Marine and a diplomat.

All they have to do is survive.

9. A Time Odyssey by Arthur C. Clarke and Stephen Baxter

What could be better than a collaboration between one of the most esteemed sci-fi writers of all time and a serious, talented up-and-coming hard-science fiction writer? Stephen Baxter had several titles under his belt before his collaboration with Arthur C. Clarke, but the A Time Odyssey trilogy they wrote together remains a fan favorite. If you haven't read this one yet, start with Time's Eye. 

In an instant, Earth is carved up in time and reassembled like a huge jigsaw puzzle. Suddenly the world becomes a patchwork of eras, from prehistory to 2037, each with its own indigenous inhabitants. The explanation for this cataclysmic event may lie in the ancient city of Babylon, where two groups of refugees from 2037—three cosmonauts and three U.N. peacekeepers—have detected strange radio signals. The peacekeepers find allies in nineteenth century British troops and in the armies of Alexander the Great. The cosmonauts join forces with the Mongol horde led by Genghis Khan. Both sides set out for Babylon, vowing to win the race for knowledge—as a powerful and mysterious entity watches, waiting.

8. Footfall by Larry Niven and Jerry Pournelle

“Niven and Pournelle are one of the seamless entertainment teams that makes it look a great deal easier than it is. That is because Larry Niven is a quality writer and Jerry Pournelle was an established scientist. When they bring their talents together the effect is fantastic and, in my opinion, very re-readable.” —Jon, Goodreads

Footfall is the first of three books on our top 10 co-written by Larry Niven and Jerry Pournelle. It introduced us to Fithp: alien invaders that resemble baby elephants with multiple prehensile trunks. The Fithp don’t sound especially menacing, but they did make last year’s list of Top 10 Most Terrifying Alien Invaders. 

It may not be the very best book to come from this team, but it’s absolutely a classic worth a reading, especially if alien invasion is your jam. 

They first appear as a series of dots on astronomical plates, heading from Saturn directly toward Earth. Since the ringed planet carries no life, scientists deduce the mysterious ship to be a visitor from another star.

The world's frantic efforts to signal the aliens go unanswered. The first contact is hostile: the invaders blast a Soviet space station, seize the survivors, and then destroy every dam and installation on Earth with a hail of asteroids.

Now the conquerors are descending on the American heartland, demanding servile surrender--or death for all humans.

7. 1633 by David Weber and Eric Flint

The 1632 series is a popular alternate history series. So popular it made our reader generated list of the Top 10 Historical Sci-Fi Books of All Time last September. Each book is written either by Eric Flint alone, or with one of a number of co-authors. Two of the earliest and most popular of these—1633 and 1634—were written with David Weber. The first book was written to be a standalone, so many who loved 1632 didn’t go on to read the collaborations which didn’t start rolling out until two years later. If you are new to the series, it’s recommended you start with 1632 before picking up 1633.

AMERICAN FREEDOM AND JUSTICE VS. SEVENTEENTH CENTURY TYRANNY

The new Confederated Principalities of Europe-an alliance between Gustavus,king of Sweden, and the West Virginia town, led by Mike Stearns, which was hurled back through time to the thirty years war - has big problems. As the greatest naval war in European history erupts, Cardinal Richelieu has created an alliance to destroy the CPE, and only American technology can save Gustavus from ruin.

6. Extinction Cycle: Dark Age by Nicholas Sansbury Smith and Anthony J. Melchiorri

“The absolute acme of achieving an amazing co-written book is quite simply that the readers and the diehard fans don't realize that it is in fact a co-written book. A smooth transition from each writer's talents and co-editing efforts must ultimately come together to provide not necessarily a much better work than either have presented before but again a seamless and fresh take on what has come before. And for me, the "Extinction Cycle: Dark Age" books by Nicholas Sansbury Smith and Anthony J. Melchiorri do just that. Of course I had read the heart-pounding books that NSS produced before but honestly, if I didn't have the cover 'credits' in front of me, I would have never noticed that the Dark Age books were being co-written. Instead, I would have just lived on in blissful ignorance, enjoying a fresh and just as exciting take on what was already a universe that I had become literally addicted to!” —Ziggy, DSF Reader

“Holy Cow my mind is just destroyed. What kind of book do you get when you combine Nicholas Sansbury Smith and Anthony J Melchiorri. A freaking barn burning , stomach churning , head exploding , heart pounding roller coaster ride from Hell.” —Billy Barfield, Goodreads

We couldn’t have said it better! Nicholas Sansbury Smith and Anthony J. Melchiorri are an incredible team. Fans of Smith's tense, emotional and high-action Extinction Cycle Universe might have picked this one up with some trepidation, wondering if the addition of a co-author would hurt the flow, depth and impact of storytelling, but anyone who knew Melchiorri's previous work, either that which he wrote alone or his previous collaboration with Smith (Orbs VI: Exodus) knew there was nothing to fear. The combination of these two writers is absolute fire! While we think everyone should read Extinction Cycle at some point, if you haven't you can still jump right in here with Extinction Shadow as Extinction Cycle: Dark Age works well as a standalone series.

Eight years ago, an engineered virus ravaged the globe, infecting and transforming humans into apex predators called Variants. Billions died, civilization collapsed, and the human race teetered on the brink of extinction. 

Nations banded together and heroes rose up to fight these abominations. On the front lines, Captain Reed Beckham and Master Sergeant Joe "Fitz" Fitzpatrick of Delta Force Team Ghost fought against the Variant hordes. With the aid of CDC Doctor Kate Lovato, they helped lead humanity to victory. 

Now, almost a decade after the end of the war, civilization has slowly clawed toward recovery. In the Allied States of America, survivors live in outposts where they have rebuilt industry, agriculture, and infrastructure. The remaining Variants are believed to be dying off under destroyed cities and the abandoned frontier. 

But evil and intelligent forces dwell in the shadows with the starving beasts, scheming to restart the extinction cycle and end humanity forever. And once again, Beckham, Fitz, and Kate will rise to fight them, joining forces with new heroes to try and save what's left of the world.

5. Empire of Man by David Weber and John Ringo

“When March Upcountry published in 2001, David Weber was well-established in Military Science Fiction, with nine books of his Honor Harrington saga plus an additional 10 novels published. In short, he was a Military SF brand name. John Ringo, his ‘apprentice’ partner in crime for March Upcountry, was a relatively new writer, having published the first two books of his Legacy of Aldenata/Posleen War series. For Ringo the rest, as they say, is history.” —Robert H. Bedford

John Ringo and David Weber have each written with other authors, but the series they wrote together Empire of Man really helped establish Ringo as a household name in science fiction. Pick this one up next time you’re looking for a fast paced, military sci-fi adventure, starting with book 1, March Upcountry. 

Roger Ramius MacClintock was young, handsome, athletic, an excellent dresser, and third in line for the Throne of Man. It probably wasn't too surprising that someone in his position should react by becoming spoiled, self‑centered, and petulant. After all, what else did he have to do with his life? Then warships of the Empire of Man's worst rivals shoot his crippled vessel out of space and Roger is shipwrecked on the planet Marduk, whose jungles are full of deadly predators and barbarian hordes with really bad dispositions. Now all Roger has to do is hike halfway around the entire planet, then capture a spaceport from the Bad Guys, somehow commandeer a starship, and then go home to Mother for explanations. Fortunately, Roger has an ace in the hole: Bravo Company of Bronze Battalion of The Empress' Own Regiment. If anyone can get him off Marduk alive, it's the Bronze Barbarians.

4. Lucifer’s Hammer by Larry Niven and Jerry Pournelle

“Every collaboration is different… Jerry and I trade scenes and choose characters, and so forth.” —Larry Niven

As well as his solo efforts, Larry Niven is known for his collaborations with other authors, a process he describes as being unique each time. Lucifer’s Hammer is one of his earlier collaborations with Jerry Pournelle and it’s interesting to read his comments on working with Pournelle, to read how they “trade scenes.” Keen readers have noted that it is pretty easy to determine which writer is responsible for which scenes (maybe especially true with Lucifer’s Hammer), but even with the obvious difference in style, the books work. 

The gigantic comet has slammed into Earth, forging earthquakes a thousand times too powerful to measure on the Richter scale, tidal waves thousands of feet high. Cities were turned into oceans; oceans turned into steam. It was the beginning of a new Ice Age and the end of civilization

But for the terrified men and women chance had saved, it was also the dawn of a new struggle for survival—a struggle more dangerous and challenging than any they had ever known….

3. The Expanse by James S. A. Corey

“‘I was trying to write enough story for a $100 million dollar MMO, which never happened,’” Franck elaborates, “‘but you wind up creating as much content as you possibly can.’” 

Abraham then stepped in and pulled Franck’s rich background into the setting for a longer narrative. Abraham explains, “‘I said, ‘You’ve done all this research; I’ve written some novels. I know how to do that. Let’s put these two together – it’s already done.’” —Excerpts from Michael Ahr’s interview with Franck and Abraham at Comic Con for Den of Geek 

In just 10 years The Expanse series by James S. A. Corey— aka writers Daniel Abraham and Ty Franck—has become a wildly successful franchise with eight books (so far), three novellas, and a popular T.V. series adapted from the novels, not to mention the Hugo nominations and, as of 2020 a Hugo win for best series. Not too shabby! Not sure where you’ve been if you haven’t heard of this one but if you haven’t or have but haven’t picked it up, start with Leviathan Wakes to see what the buzz is about! 

Jim Holden is XO of an ice miner making runs from the rings of Saturn to the mining stations of the Belt. When he and his crew stumble upon a derelict ship, the Scopuli, they find themselves in possession of a secret they never wanted. A secret that someone is willing to kill for—and kill on a scale unfathomable to Jim and his crew. War is brewing in the system unless he can find out who left the ship and why.

2. The Mote in God’s Eye by Larry Niven and Jerry Pournelle

“I had 4 kids to get through college. So I do journalism and write articles -- or did, until we hit the bestseller list. I told Niven stick with me and I'll make you rich and famous. He was already rich.” —Jerry Pournelle

The Mote in God’s Eye was the first in the three book Moties series and, relevant to this poll, the first of many collaborations between longtime friends Larry Niven and Jerry Pournelle. True to Pournelle’s prediction, the work they produced together eventually made both of them rich (and famous) and this, their first joint effort, was lauded by Robert A. Heinlein as being “a very important novel, possibly the best contact-with-aliens story ever written.” Not a bad way to kick off a partnership!

In 3016, the 2nd Empire of Man spans hundreds of star systems, thanks to faster-than-light Alderson Drive. Intelligent beings are finally found from the Mote, an isolated star in a thick dust cloud. The bottled-up ancient civilization, at least one million years old, are welcoming, kind, yet evasive, with a dark problem they have not solved in over a million years.

1.Galaxy’s Edge by Jason Anspach and Nick Cole

“Jason came to my attention because his writing is outstanding. He really loves the art of the story. And he’s got an excellent narrative voice and one of the most agile minds I’ve encountered. He’s the David Spade to my Chris Farley.”  —Nick Cole

And so began one of the most kick-ass modern day sci-fi collaborations. Readers of Jason Anspach and Nick Cole’s Galaxy’s Edge quickly turn into die-hard fans: fans, who are richly rewarded as this writing duo manages an incredible publishing schedule, turning out book after book, each as fast-paced and engrossing as the last. If you haven't read the series yet, begin at the beginning, with Legionnaire.

The Galaxy is a Dumpster Fire.

A hot, stinking, dumpster fire. And most days I don’t know if the legionnaires are putting out the flames, or fanning them into an inferno.

A hostile force ambushes Victory Company during a reconnaissance-in-force deep inside enemy territory. Stranded behind enemy lines, a sergeant must lead a band of survivors against merciless insurgents on a deadly alien world somewhere along the galaxy’s edge. With no room for error, the Republic’s elite fighting force must struggle to survive under siege while waiting on a rescue that might never come.
