We love the feeling of discovering a fresh new literary voice! How about you? 2021 has seen the release of some great debuts and they are too good not to share. And so it is in that spirit with which we present our list of 10 sci-fi books by emerging authors that you don't want to miss! 

The Effort by Claire Holroyde

Release Date: January 12, 2021

When dark comet UD3 was spotted near Jupiter's orbit, its existence was largely ignored. But to individuals who knew better -- scientists like Benjamin Schwartz, manager of NASA's Center for Near-Earth Object Studies -- the threat this eight-kilometer comet posed to the survival of the human race was unthinkable. The 150-million-year reign of the dinosaurs ended when an asteroid impact generated more than a billiontimes the energy of an atomic bomb.

What would happen to Earth's seven billion inhabitants if a similar event were allowed to occur?

Ben and his indomitable girlfriend Amy Kowalski fly to South America to assemble an international counteraction team, whose notable recruits include Love Mwangi, a UN interpreter and nomad scholar, and Zhen Liu, an extraordinary engineer from China's national space agency. At the same time, on board a polar icebreaker life continues under the looming shadow of comet UD3. Jack Campbell, a photographer for National Geographic, works to capture the beauty of the Arctic before it is gone forever. Gustavo Wayãpi, a Nobel Laureate poet from Brazil, struggles to accept the recent murder of his beloved twin brother. And Maya Gutiérrez, an impassioned marine biologist is -- quite unexpectedly -- falling in love for the first time.

Together, these men and women must fight to survive in an unknown future with no rules and nothing to be taken for granted. They have two choices: neutralize the greatest threat the world has ever seen (preferably before mass hysteria hits or world leaders declare World War III) or come to terms with the annihilation of humanity itself.

Their mission is codenamed The Effort.

Winter's Orbit by Everina Maxwell

Release Date: February 2, 2021

Prince Kiem, a famously disappointing minor royal and the Emperor's least favorite grandchild, has been called upon to be useful for once. He's commanded to fulfill an obligation of marriage to the representative of the Empire's newest and most rebellious vassal planet. His future husband, Count Jainan, is a widower and murder suspect.

Neither wants to be wed, but with a conspiracy unfolding around them and the fate of the empire at stake they will have to navigate the thorns and barbs of court intrigue, the machinations of war, and the long shadows of Jainan's past, and they'll have to do it together.

So begins a legendary love story amid the stars.

One Day as a Lion by Jonathan E. Hernandez

Release Date: March 2, 2021

Two civilizations clash. A rebellion grows. The fate of the galaxy hangs in the balance.

Technical Chief "Pappy" Gunther is a grizzled, burning out commando in the United Earth Armed Forces. He ponders a return to civilian life, yet feels a strong sense of belonging to his elite team. When colonists on a far-flung world request aid, a task force from several allied systems is assembled. Pappy and his crack unit are sent to investigate, and to engage a mysterious alien force from beyond.

Talks-To-His-Spear is the warrior-caste champion of a matriarchal space empire called the Regime. Leading an army of fanatical, genetically-enhanced super soldiers, he dreams of dying in battle for the glory of his Queen. However, he’s beginning to question the motives of this new campaign, and fears that he may have to compromise his own deep sense of honor in order to fulfill his tasks.

Nobody expected the two alien cultures to have so much in common, and for friendships and alliances to form alongside rivalries. However, when Pappy discovers a rebellion spanning worlds, everything changes. The growing insurrection threatens to tear the Regime—and the galaxy—apart.

We Are Watching Eliza Bright by A.E. Osworth

Release Date: April 13, 2021

Eliza Bright is living the dream as an elite video game coder at Fancy Dog Games, the first woman to ascend that high in the ranks—and some people want to make sure she’s the last. To her friends, Eliza Bright is a brilliant, self-taught coder bravely calling out the misogyny that pervades her workplace and industry. To the men who see her very presence as a threat, Eliza Bright is a woman who needs to be destroyed to protect the game they love.

When Eliza’s report of workplace harassment is quickly dismissed, she's forced to take her frustrations to a journalist who blasts her story across the internet. She's fired and doxxed, and becomes a rallying figure for women everywhere. But she's also enraged the beast comprised of online male gamers—their unreliable chorus narrates our story. Soon, Eliza is in the cross-hairs of the gaming community, threatened and stalked as they monitor her every move online and across New York City.

As the violent power of the angry male collective descends upon everyone in Eliza's life, it becomes increasingly difficult to know who to trust, even when she's eventually taken in and protected by an under-the-radar Collective known as the Sixsterhood. The violence moves from cyberspace to the real world, thanks to a vicious male super-fan known only as The Inspectre, determined to exact his revenge on behalf of men everywhere. We watch alongside the Sixsterhood and subreddit keyboard warriors as this dramatic cat-and-mouse game plays out to its violent and inevitable conclusion in this thrilling story of resilience and survival.

The End of Men by Christina Sweeney-Baird

Release Date: April 27, 2021

Only men carry the virus. Only women can save us all.

The year is 2025, and a mysterious virus has broken out in Scotland--a lethal illness that seems to affect only men. When Dr. Amanda MacLean reports this phenomenon, she is dismissed as hysterical. By the time her warning is heeded, it is too late. The virus becomes a global pandemic--and a political one. The victims are all men. The world becomes alien--a women's world.

What follows is the immersive account of the women who have been left to deal with the virus's consequences, told through first-person narratives. Dr. MacLean; Catherine, a social historian determined to document the human stories behind the "male plague"; intelligence analyst Dawn, tasked with helping the government forge a new society; and Elizabeth, one of many scientists desperately working to develop a vaccine. Through these women and others, we see the uncountable ways the absence of men has changed society, from the personal--the loss of husbands and sons--to the political--the changes in the workforce, fertility, and the meaning of family.

How to Mars by David Ebenbach

Release Date: May 25, 2021

For the six lucky scientists selected by the Destination Mars! corporation, a one-way ticket to Mars—in exchange for a lifetime of research—was an absolute no-brainer. The incredible opportunity was clearly worth even the most absurdly tedious screening process. Perhaps worth following the strange protocols in a nonsensical handbook written by an eccentric billionaire. Possibly even worth their constant surveillance, the video of which is carefully edited into a ratings-bonanza back on Earth.

But it turns out that after a while even scientists can get bored of science. Tempers begin to fray; unsanctioned affairs blossom. When perfectly good equipment begins to fail, the Marsonauts are faced with a possibility that their training just cannot explain.

Irreverent, poignant, and perfectly weird, David Ebenbach’s exciting debut science-fiction outing, like a mission to Mars, is an incredible trip you will never forget.

Gearbreakers by Zoe Hana Mikuta

Release Date: June 29, 2021

We went past praying to deities and started to build them instead...

The shadow of Godolia's tyrannical rule is spreading, aided by their giant mechanized weapons known as Windups. War and oppression are everyday constants for the people of the Badlands, who live under the thumb of their cruel Godolia overlords.

Eris Shindanai is a Gearbreaker, a brash young rebel who specializes in taking down Windups from the inside. When one of her missions goes awry and she finds herself in a Godolia prison, Eris meets Sona Steelcrest, a cybernetically enhanced Windup pilot. At first Eris sees Sona as her mortal enemy, but Sona has a secret: She has intentionally infiltrated the Windup program to destroy Godolia from within.

As the clock ticks down to their deadliest mission yet, a direct attack to end Godolia's reign once and for all, Eris and Sona grow closer—as comrades, friends, and perhaps something more...

The All-Consuming World by Cassandra Khaw

Release Date: September 7, 2021

Maya has died and been resurrected into countless cyborg bodies through the years of a long, dangerous career with the infamous Dirty Dozen, the most storied crew of criminals in the galaxy, at least before their untimely and gruesome demise. Decades later, she and her diverse team of broken, diminished outlaws must get back together to solve the mystery of their last, disastrous mission and to rescue a missing and much-changed comrade . . . but they’re not the only ones in pursuit of the secret at the heart of the planet Dimmuborgir.

The highly evolved AI of the galaxy have their own agenda and will do whatever it takes to keep humanity from ever regaining control. As Maya and her comrades spiral closer to uncovering the AIs’ vast conspiracy, this band of violent women—half-clone and half-machine—must battle their own traumas and a universe of sapient ageships who want them dead, in order to settle their affairs once and for all.

Welcome to The All-Consuming World, the debut novel of acclaimed writer Cassandra Khaw. With this explosive and introspective exploration of humans and machines, life and death, Khaw takes their rightful place next to such science fiction luminaries as Ann Leckie, Ursula Le Guin, and Kameron Hurley.

The Body Scout by Lincoln Michel

Release Date: September 21, 2021

In the future you can have any body you want—as long as you can afford it.

But in a New York ravaged by climate change and repeat pandemics, Kobo is barely scraping by. He scouts the latest in gene-edited talent for Big Pharma-owned baseball teams, but his own cybernetics are a decade out of date and twin sister loan sharks are banging down his door. Things couldn't get much worse.

Then his brother—Monsanto Mets slugger J.J. Zunz—is murdered at home plate.

Determined to find the killer, Kobo plunges into a world of genetically modified CEOs, philosophical Neanderthals, and back-alley body modification, only to quickly find he's in a game far bigger and more corrupt than he imagined. To keep himself together while the world is falling apart, he'll have to navigate a time where both body and soul are sold to the highest bidder.
