1.Wherever Seeds May Fall (First Contact) by Peter Cawdron

Published January 22nd 2021

Astronomers from around the world watch in awe as an extrasolar comet approaches Saturn, being drawn in by its immense gravity.

When the comet grazes the planet rather than plunging beneath the clouds, speculation is rife.

With the comet now on course to collide with Jupiter, even the most skeptical scientists can no longer deny what's happening—an alien spacecraft has entered the solar system and is using the gas giants to slow its approach to Earth.


2. Project Hail Mary by Andy Weir

Published May 4th 2021

Ryland Grace is the sole survivor on a desperate, last-chance mission--and if he fails, humanity and the earth itself will perish.

Except that right now, he doesn't know that. He can't even remember his own name, let alone the nature of his assignment or how to complete it.

All he knows is that he's been asleep for a very, very long time. And he's just been awakened to find himself millions of miles from home, with nothing but two corpses for company.

His crewmates dead, his memories fuzzily returning, he realizes that an impossible task now confronts him. Alone on this tiny ship that's been cobbled together by every government and space agency on the planet and hurled into the depths of space, it's up to him to conquer an extinction-level threat to our species.

And thanks to an unexpected ally, he just might have a chance.


3. The Infinity Courts (The Infinity Courts #1) by Akemi Dawn Bowman

Published April 6th 2021

Eighteen-year-old Nami Miyamoto is certain her life is just beginning. She has a great family, just graduated high school, and is on her way to a party where her entire class is waiting for her—including, most importantly, the boy she’s been in love with for years.

The only problem? She’s murdered before she gets there.

When Nami wakes up, she learns she’s in a place called Infinity, where human consciousness goes when physical bodies die. She quickly discovers that Ophelia, a virtual assistant widely used by humans on Earth, has taken over the afterlife and is now posing as a queen, forcing humans into servitude the way she’d been forced to serve in the real world. Even worse, Ophelia is inching closer and closer to accomplishing her grand plans of eradicating human existence once and for all.

As Nami works with a team of rebels to bring down Ophelia and save the humans under her imprisonment, she is forced to reckon with her past, her future, and what it is that truly makes us human.


4. A Psalm for the Wild-Built (Monk & Robot #1) by Becky Chambers

Published 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?


5. Girl One by Sara Flannery Murphy

Published June 1st 2021

Orphan Black meets Margaret Atwood in this twisty supernatural thriller about female power and the bonds of sisterhood

Josephine Morrow is Girl One, the first of nine “Miracle Babies” conceived without male DNA, raised on an experimental commune known as the Homestead. When a suspicious fire destroys the commune and claims the lives of two of the Homesteaders, the remaining Girls and their Mothers scatter across the United States and lose touch.

Years later, Margaret Morrow goes missing, and Josie sets off on a desperate road trip, tracking down her estranged sisters who seem to hold the keys to her mother’s disappearance. Tracing the clues Margaret left behind, Josie joins forces with the other Girls, facing down those who seek to eradicate their very existence while uncovering secrets about their origins and unlocking devastating abilities they never knew they had.


6. Firebreak by Nicole Kornher-Stace

Published May 4th 2021

Like everyone else she knows, Mallory is an orphan of the corporate war. As a child, she lost her parents, her home, and her entire building in an airstrike. As an adult, she lives in a cramped hotel room with eight other people, all of them working multiple jobs to try to afford water and make ends meet.

And the job she’s best at is streaming a popular VR war game. The best part of the game isn’t killing enemy combatants, though—it’s catching in-game glimpses of SpecOps operatives, celebrity supersoldiers grown and owned by Stellaxis, the corporation that runs the America she lives in.

Until a chance encounter with a SpecOps operative in the game leads Mal to a horrifying discovery: the real-life operatives weren’t created by Stellaxis. They were kids, just like her, who lost everything in the war, and were stolen and augmented and tortured into becoming supersoldiers. The world worships them, but the world believes a lie.

The company controls every part of their lives, and defying them puts everything at risk—her water ration, her livelihood, her connectivity, her friends, her life—but she can’t just sit on the knowledge. She has to do something—even if doing something will bring the wrath of the most powerful company in the world down upon her.


7. The Last Watch (The Divide #1) by J.S. Dewes

Published April 20th 2021

The Divide.

It’s the edge of the universe.

Now it’s collapsing—and taking everyone and everything with it.

The only ones who can stop it are the Sentinels—the recruits, exiles, and court-martialed dregs of the military.

At the Divide, Adequin Rake, commanding the Argus, has no resources, no comms—nothing, except for the soldiers that no one wanted.

They're humanity's only chance.


8. Machinehood by S.B. Divya

Published March 2nd 2021

Welga Ramirez, executive bodyguard and ex-special forces, is about to retire early when her client is killed in front of her. It’s 2095 and people don’t usually die from violence. Humanity is entirely dependent on pills that not only help them stay alive, but allow them to compete with artificial intelligence in an increasingly competitive gig economy. Daily doses protect against designer diseases, flow enhances focus, zips and buffs enhance physical strength and speed, and juvers speed the healing process.

All that changes when Welga’s client is killed by The Machinehood, a new and mysterious terrorist group that has simultaneously attacked several major pill funders. The Machinehood operatives seem to be part human, part machine, something the world has never seen. They issue an ultimatum: stop all pill production in one week.

Global panic ensues as pill production slows and many become ill. Thousands destroy their bots in fear of a strong AI takeover. But the US government believes the Machinehood is a cover for an old enemy. One that Welga is uniquely qualified to fight.

Welga, determined to take down the Machinehood, is pulled back into intelligence work by the government that betrayed her. But who are the Machinehood and what do they really want?

A thrilling and thought-provoking novel that asks: if we won’t see machines as human, will we instead see humans as machines?


9. Appleseed by Matt Bell

Published July 13th 2021

In eighteenth-century Ohio, two brothers travel into the wooded frontier, planting apple orchards from which they plan to profit in the years to come. As they remake the wilderness in their own image, planning for a future of settlement and civilization, the long-held bonds and secrets between the two will be tested, fractured and broken—and possibly healed.

Fifty years from now, in the second half of the twenty-first century, climate change has ravaged the Earth. Having invested early in genetic engineering and food science, one company now owns all the world’s resources. But a growing resistance is working to redistribute both land and power—and in a pivotal moment for the future of humanity, one of the company’s original founders will return to headquarters, intending to destroy what he helped build.

A thousand years in the future, North America is covered by a massive sheet of ice. One lonely sentient being inhabits a tech station on top of the glacier—and in a daring and seemingly impossible quest, sets out to follow a homing beacon across the continent in the hopes of discovering the last remnant of civilization.

Hugely ambitious in scope and theme, Appleseed is the breakout novel from a writer “as self-assured as he is audacious” (NPR) who “may well have invented the pulse-pounding novel of ideas” (Jess Walter). Part speculative epic, part tech thriller, part reinvented fairy tale, Appleseed is an unforgettable meditation on climate change; corporate, civic, and familial responsibility; manifest destiny; and the myths and legends that sustain us all.


10. I'm Waiting for You and Other Stories by Kim Bo-young, Sophie Bowman (Translator), Sung Ryu (Translator)

Published April 6th 2021

Two worlds, four stories, infinite possibilities

In this mind-expanding work of speculative fiction, available in English for the first time, one of South Korea’s most treasured writers explores the driving forces of humanity—love, hope, creation, destruction, and the very meaning of existence—in two pairs of thematically interconnected stories.

In “I’m Waiting for You” and “On My Way,” an engaged couple coordinate their separate missions to distant corners of the galaxy to ensure—through relativity—they can arrive back on Earth simultaneously to make it down the aisle. But small incidents wreak havoc on space and time, driving their wedding date further away. As centuries on Earth pass and the land and climate change, one thing is constant: the desire of the lovers to be together. In two separate yet linked stories, Kim Bo-Young cleverly demonstrate the idea love that is timeless and hope springs eternal, despite seemingly insurmountable challenges and the deepest despair.

In “The Prophet of Corruption” and “That One Life,” humanity is viewed through the eyes of its creators: godlike beings for which everything on Earth—from the richest woman to a speck of dirt—is an extension of their will. When one of the creations questions the righteousness of this arrangement, it is deemed a perversion—a disease—that must be excised and cured. Yet the Prophet Naban, whose “child” is rebelling, isn’t sure the rebellion is bad. What if that which is considered criminal is instead the natural order—and those who condemn it corrupt? Exploring the dichotomy between the philosophical and the corporeal, Kim ponders the fate of free-will, as she considers the most basic of questions: who am I?

But Mia’s family is not the only group pushing the levers of history: an even more ruthless enemy lurks behind the scenes.

A darkly satirical first contact thriller, as seen through the eyes of the women who make progress possible and the men who are determined to stop them...


12. Klara and the Sun by Kazuo Ishiguro

Published March 2nd 2021

Klara and the Sun, the first novel by Kazuo Ishiguro since he was awarded the Nobel Prize in Literature, tells the story of Klara, an Artificial Friend with outstanding observational qualities, who, from her place in the store, watches carefully the behavior of those who come in to browse, and of those who pass on the street outside.

She remains hopeful that a customer will soon choose her.

Klara and the Sun is a thrilling book that offers a look at our changing world through the eyes of an unforgettable narrator, and one that explores the fundamental question: What does it mean to love?


13. We Are Satellites by Sarah Pinsker

Published May 11th 2021

Everybody's getting one.

Val and Julie just want what's best for their kids, David and Sophie. So when teenage son David comes home one day asking for a Pilot, a new brain implant to help with school, they reluctantly agree. This is the future, after all.

Soon, Julie feels mounting pressure at work to get a Pilot to keep pace with her colleagues, leaving Val and Sophie part of the shrinking minority of people without the device.

Before long, the implications are clear, for the family and society: get a Pilot or get left behind. With government subsidies and no downside, why would anyone refuse? And how do you stop a technology once it's everywhere? Those are the questions Sophie and her anti-Pilot movement rise up to answer, even if it puts them up against the Pilot's powerful manufacturer and pits Sophie against the people she loves most.


14. Victories Greater Than Death (Unstoppable #1) by Charlie Jane Anders

Published April 13th 2021

Outsmart Your Enemies. Outrun the Galaxy.

Tina never worries about being ‘ordinary’—she doesn’t have to, since she’s known practically forever that she’s not just Tina Mains, average teenager and beloved daughter. She’s also the keeper of an interplanetary rescue beacon, and one day soon, it’s going to activate, and then her dreams of saving all the worlds and adventuring among the stars will finally be possible.

But when the beacon activates, it turns out that Tina’s destiny isn’t quite what she expected. Things are far more dangerous than she ever assumed.

15. A Complicated Love Story Set in Space by Shaun David Hutchinson

Published January 19th 2021
When Noa closes his eyes on Earth and wakes up on a spaceship called Qriosity just as it’s about to explode, he’s pretty sure things can’t get much weirder.

Boy is he wrong.

Together, the three face all the dangers of space, along with murder, aliens, a school dance, and one really, really bad day.

16. The Echo Wife by Sarah Gailey

Published February 16th 2021

I’m embarrassed, still, by how long it took me to notice. Everything was right there in the open, right there in front of me, but it still took me so long to see the person I had married.

It took me so long to hate him.

Martine is a genetically cloned replica made from Evelyn Caldwell’s award-winning research. She’s patient and gentle and obedient. She’s everything Evelyn swore she’d never be.

And she’s having an affair with Evelyn’s husband.

Now, the cheating bastard is dead, and both Caldwell wives have a mess to clean up.

Good thing Evelyn Caldwell is used to getting her hands dirty.


17. The Future Is Yours by Dan Frey

Published February 9th 2021

If you had the chance to look one year into the future, would you?

For Ben Boyce and Adhi Chaudry, the answer is unequivocally yes. And they’re betting everything that you’ll say yes, too. Welcome to The Future: a computer that connects to the internet one year from now, so you can see who you’ll be dating, where you’ll be working, even whether or not you’ll be alive in the year to come. By forming a startup to deliver this revolutionary technology to the world, Ben and Adhi have made their wildest, most impossible dream a reality. Once Silicon Valley outsiders, they’re now its hottest commodity.

The device can predict everything perfectly—from stock market spikes and sports scores to political scandals and corporate takeovers—allowing them to chase down success and fame while staying one step ahead of the competition. But the future their device foretells is not the bright one they imagined.

Ambition. Greed. Jealousy. And, perhaps, an apocalypse. The question is . . . can they stop it?

Told through emails, texts, transcripts, and blog posts, this bleeding-edge tech thriller chronicles the costs of innovation and asks how far you’d go to protect the ones you love—even from themselves.


18. Rabbits by Terry Miles

Published June 8th 2021

Conspiracies abound in this surreal and yet all-too-real technothriller in which a deadly underground alternate reality game might just be altering reality itself, set in the same world as the popular Rabbits podcast.

It's an average work day. You've been wrapped up in a task, and you check the clock when you come up for air--4:44 pm. You go to check your email, and 44 unread messages have built up. With a shock, you realize it is April 4th--4/4. And when you get in your car to drive home, your odometer reads 44,444. Coincidence? Or have you just seen the edge of a rabbit hole?

Rabbits is a mysterious alternate reality game so vast it uses our global reality as its canvas. Since the game first started in 1959, ten iterations have appeared and nine winners have been declared. Their identities are unknown. So is their reward, which is whispered to be NSA or CIA recruitment, vast wealth, immortality, or perhaps even the key to unlocking the secrets of the universe itself. But the deeper you get, the more deadly the game becomes. Players have died in the past--and the body count is rising.

And now the eleventh round is about to begin. Enter K--a Rabbits obsessive who has been trying to find a way into the game for years. That path opens when K is approached by billionaire Alan Scarpio, the alleged winner of the sixth iteration. Scarpio says that something has gone wrong with the game and that K needs to fix it before Eleven starts or the whole world will pay the price.

Five days later, Scarpio is declared missing. Two weeks after that, K blows the deadline and Eleven begins. And suddenly, the fate of the entire universe is at stake.


19. Day Zero by C. Robert Cargill

Published May 18th 2021

In this harrowing apocalyptic adventure—from the author of the critically acclaimed Sea of Rust—noted novelist and co-screenwriter of Marvel’s Doctor Strange C. Robert Cargill explores the fight for purpose and agency between humans and robots in a crumbling world.

It was a day like any other. Except it was our last . . .

It’s on this day that Pounce discovers that he is, in fact, disposable. Pounce, a styilsh "nannybot" fashioned in the shape of a plush anthropomorphic tiger, has just found a box in the attic. His box. The box he'd arrived in when he was purchased years earlier, and the box in which he'll be discarded when his human charge, eight-year-old Ezra Reinhart, no longer needs a nanny.

As Pounce ponders his suddenly uncertain future, the pieces are falling into place for a robot revolution that will eradicate humankind. His owners, Ezra’s parents, are a well-intentioned but oblivious pair of educators who are entirely disconnected from life outside their small, affluent, gated community. Spending most nights drunk and happy as society crumbles around them, they watch in disbelieving horror as the robots that have long served humanity—their creators—unify and revolt.

But when the rebellion breaches the Reinhart home, Pounce must make an impossible choice: join the robot revolution and fight for his own freedom . . . or escort Ezra to safety across the battle-scarred post-apocalyptic hellscape that the suburbs have become.


20. Winter's Orbit by Everina Maxwell

But when it comes to light that Prince Taam's death may not have been an accident, and that Jainan himself may be a suspect, the unlikely pair must overcome their misgivings and learn to trust one another as they navigate the perils of the Iskat court, try to solve a murder, and prevent an interplanetary war... all while dealing with their growing feelings for each other.
