About the book
2019 HUGO AWARD FINALIST, BEST NOVEL
The Hitchhiker's Guide to the Galaxy meets the joy and glamour of Eurovision in bestselling author Catherynne M. Valente's science fiction spectacle, where sentient races compete for glory in a galactic musical contest…and the stakes are as high as the fate of planet Earth.
A century ago, the Sentience Wars tore the galaxy apart and nearly ended the entire concept of intelligent space-faring life. In the aftermath, a curious tradition was invented—something to cheer up everyone who was left and bring the shattered worlds together in the spirit of peace, unity, and understanding.
Once every cycle, the great galactic civilizations gather for the Metagalactic Grand Prix—part gladiatorial contest, part beauty pageant, part concert extravaganza, and part continuation of the wars of the past. Species far and wide compete in feats of song, dance and/or whatever facsimile of these can be performed by various creatures who may or may not possess, in the traditional sense, feet, mouths, larynxes, or faces. And if a new species should wish to be counted among the high and the mighty, if a new planet has produced some savage group of animals, machines, or algae that claim to be, against all odds, sentient? Well, then they will have to compete. And if they fail? Sudden extermination for their entire species.
This year, though, humankind has discovered the enormous universe. And while they expected to discover a grand drama of diplomacy, gunships, wormholes, and stoic councils of aliens, they have instead found glitter, lipstick, and electric guitars. Mankind will not get to fight for its destiny—they must sing.
Decibel Jones and the Absolute Zeroes have been chosen to represent their planet on the greatest stage in the galaxy. And the fate of Earth lies in their ability to rock.

About the book
What if humanity’s next stage of evolution wasn’t discovered…
But engineered?
Elliot Voss spent decades pursuing a singular vision.
Until he found a way to rewrite the rules of life itself.
In secret, the billionaire futurist cured disease.
Then he cured aging.
Then… he vanished.
Now, without warning to anyone but a chosen few, the world is preparing to change.
The System will overlay the entire planet, bringing real stats, real levels, and three paths to evolution: Combat Class, Profession, and Race. But this isn’t a game. No do-overs. No respawns. And no one—not even the elite—is exempt.
As a handpicked team enters the first Tutorial shard, they must race to prepare Earth for its eventual induction into The System.
But Voss didn’t just want humanity to become stronger. He wanted it to become wiser. More compassionate. Worthy of the gifts to come.
In the end,
No one will remain unchanged.

About the book
If Shatter Me and Divergent had a morally gray baby raised by ghosts—it would be Avidian.
This is a spicy, binge-worthy romantasy set in a dystopian world where she’s forced to solve a murder using her rare ability to see the dead—and the man offering her a way out might be hiding the most dangerous secret of all.
I can see the dead. They tell me their secrets. But this time, their secrets might get me killed.
My name is Kat Sinclair, and the Volkov family owns me. People like me, born with special abilities, are called Avids. But my gift doesn’t spare me from the demands of Marco Volkov, the ruthless family patriarch who keeps me in line with the ever-present threat of violence.
When a grisly double murder involving a family nephew and a cook shakes the household, I’m forced to uncover the truth. The whispers of the dead reveal more than I bargained for, unearthing secrets that could destroy the Volkovs—and me.
But I met a charming stranger who might be able to help. Except he doesn’t know about my gift, my scars, or the dark past I can’t escape. But in his eyes, I see something I thought I’d lost long ago—hope.
If I want to escape, I’ll have to play along. But this murder might be hiding something even more dangerous. If I’m not careful, I’ll be the next one the dead are whispering about.

About the book
An unlikely savior searching for an angel in the midst of Hell...
As a convict serving a life sentence, I shouldn't be playing the hero to the prison warden's damsel-in-distress daughter. But with ninety-nine percent of the population projected to die from a rapidly-spreading virus and society falling into chaos, the desperate, dying father’s options are limited. And since I'm immune to the virus, he puts his daughter's life in my hands with one simple directive: Find her.
I only know the warden's daughter from a photograph, but she glows like she was Heaven-sent. Protecting her gives me purpose in this godforsaken world where a sinister and uncannily-organized faction is rising from the rubble—taking control in a lawless land and rounding up the few survivors. When I finally find her, will the young woman with the innocent smile and ocean-blue eyes still shine from within? Or will the spiraling darkness snuff out her light for good?
FIND HER is a standalone, steamy apocalypse romance novel with a guaranteed happily-ever-after.

Four years after vanishing on Bodmin Moor, Mal reappears, pulling her friend Lee—and MI5 investigator Julian Sabreur—into a mystery tied to physicist Kay Amal Khan’s research on parallel Earths.

Clarke Award winner.
Choose your retailer
About the book
From the Arthur C. Clarke Award-winning Adrian Tchaikovsky, The Doors of Eden is an extraordinary feat of the imagination and a page-turning adventure about parallel universes and the monsters that they hide. They thought we were safe. They were wrong. Four years ago, two girls went looking for monsters on Bodmin Moor. Only one came back. Lee thought she'd lost Mal, but now she's miraculously returned. But what happened that day on the moors? And where has she been all this time? Mal's reappearance hasn't gone unnoticed by MI5 officers either, and Lee isn't the only one with questions. Julian Sabreur is investigating an attack on top physicist Kay Amal Khan. This leads Julian to clash with agents of an unknown power - and they may or may not be human. His only clue is grainy footage, showing a woman who supposedly died on Bodmin Moor. Dr Khan's research was theoretical; then she found cracks between our world and parallel Earths. Now these cracks are widening, revealing extraordinary creatures. And as the doors crash open, anything could come through. "Tchaikovsky weaves a masterful tale... a suspenseful joyride through the multiverse." (Booklist)

Caitlyn Can’t Die
Dystopian · Sci-Fi
Our take
In Caitlyn Can’t Die, a Halloween disaster destroys the world and leaves Caitlyn wishing she had not survived. When Riley refuses to abandon her after finding her wounded, the two opposites become uneasy allies in a collapsing landscape where people pose more danger than monsters. With 4.3 Amazon stars and strong Goodreads ratings, this survival romance strikes an emotional chord.
Choose your retailer
About the book
Since when did surviving the apocalypse become a good thing?
Caitlyn was doing okay before the end of the world. She had a decent job, dated around, and there was nothing a glass (bottle) of wine couldn't fix. When a Halloween haunted house proves to have real-life monsters turning everyone into creatures with black goo for blood, she manages to survive a few months on pure luck. The thing is... she doesn't want to anymore.
Riley doesn't leave people behind. It's not in his nature to give up, so when he finds a woman bleeding out in the woods, he stops to help. It's only when she wakes up the next day, furious that she isn't dead, that he realizes she didn't want to be saved. The duo are complete opposites who can't stop arguing with one another about how to survive, or if they even want to anymore.
It's not just the lack of heat, clean water, and tampons. This new world is horrible for those left alive. People have become more dangerous than the beasts they are running from. Who would want to live like this? But day after day, and despite all odds, Caitlyn and Riley keep going. They start to wonder if the lack of every modern convenience combined with the threat of impending doom isn't all that bad. They have each other, and maybe, that's enough.

About the book
WINNER OF THE LOCUS AWARD • The bestselling author of the Mars trilogy boldly reimagines the past seven hundred years in this “exceptional and engrossing” (New York Post) saga, constructing a world vastly different from the one we know. . .
“A thoughtful, magisterial alternate history from one of science fiction’s most important writers.”—The New York Times Book Review
It is the fourteenth century and one of the most apocalyptic events in human history is set to occur—the coming of the Black Death. History teaches us that a third of Europe’s population was destroyed. But what if the plague had killed 99 percent of the population instead? How would the world have changed? The Years of Rice and Salt is a look at the history that could have been—one that stretches across centuries, sees dynasties and nations rise and crumble, and spans horrible famine and magnificent innovation.
Through the eyes of soldiers and kings, explorers and philosophers, inventors and exiles, renowned storyteller Kim Stanley Robinson navigates a world where Buddhism and Islam are the most influential and practiced religions, while Christianity is a mere historical footnote. Probing the most profound questions as only he can, Robinson shines his extraordinary light on the place of religion, culture, power—and even love—in this bold new world.

About the book
"A love story spanning multiple millenniums, life-forms and variations on immortality, the book posits Victorian poetry as a weapon of empire, insists on nature's resilience in the face of genocide, and manipulates prose into something like a new language....Toward Eternity recognizes both the building and burning of bridges." -New York Times
*A PARADE, LITHUB, and CHICAGO REVIEW OF BOOKS Best New Book. *An AUDIOFILE EARPHONES AWARD WINNER.
Negotiating the terrain of Kazuo Ishiguro’s Klara and the Sun and Emily St. John Mandel’s Sea of Tranquility, a brilliant, haunting speculative novel from a #1 New York Times bestselling translator that sets out to answer the question: What does it mean to be human in a world where technology is quickly catching up to biology?
In a near-future world, a new technological therapy is quickly eradicating cancer. The body’s cells are entirely replaced with nanites—robot or android cells which not only cure those afflicted but leaves them virtually immortal.
Literary researcher Yonghun teaches an AI how to understand poetry and creates a living, thinking machine he names Panit, meaning Beloved, in honor of his husband. When Yonghun—himself a recipient of nanotherapy—mysteriously vanishes into thin air and then just as suddenly reappears, the event raises disturbing questions. What happened to Yonghun, and though he’s returned, is he really himself anymore?
When Dr. Beeko, the scientist who holds the patent to the nanotherapy technology, learns of Panit, he transfers its consciousness from the machine into an android body, giving it freedom and life. As Yonghun, Panit, and other nano humans thrive—and begin to replicate—their development will lead them to a crossroads and a choice with existential consequences.
Exploring the nature of intelligence and the unexpected consequences of progress, the meaning of personhood and life, and what we really have to fear from technology and the future, Toward Eternity is a gorgeous, thought-provoking novel that challenges the notion of what makes us human—and how love survives even the end of that humanity.
