About the book
Part alien invasion story, part buddy comedy, and part workplace satire, After The Fall by Edward Ashton, author of Mickey7 (inspiration for the film Mickey 17), asks an important question: would humans really make great pets?
Humans must be silent. Humans must be obedient. Humans must be good.
All his life, John has tried to live by those rules. Most days, it’s not too difficult. A hundred and twenty years after The Fall, and a hundred years after the grays swept in to pick the last dregs of humanity out of the wreckage of a ruined world, John has found himself bonded to Martok Barden nee Black Hand, one of the "good" grays. Sure, Martok is broke, homeless, and borderline manic, but he’s always treated John like an actual person, and sometimes like a friend. It’s a better deal than most humans get.
But when Martok puts John’s bond up as collateral against an abandoned house in the woods that he hopes to turn into a wilderness retreat for wealthy grays, John learns that there are limits to Martok’s friendship. Soon he finds himself caught between an underworld boss who thinks Martok is something that he very much is not, a girl who was raised by feral humans and has nothing but contempt for pets like John, and Martok himself, whose delusions of grandeur seem to be finally catching up with him.
Also, not for nothing, something in the woods has been killing people.
John has sixty days before Martok’s loan comes due to unravel the mystery of how humans wound up holding the wrong end of the domestication stick and find a way to turn Martok’s half-baked plans into profit enough to buy back his life, all while avoiding getting butchered by feral humans or having his head crushed by an angry gray. Easy peasy, right?

About the book
From the New York Times bestselling author of Tokyo Ever After comes “an endearing, lightly magical romantic comedy” (Kirkus Reviews) about a girl who starts receiving letters from the love of her life—writing to her from years in the future.
What if your true love could write to you from the future?
Seventeen-year-old Emma Nakamura-Thatcher doesn’t believe in love, not after her parents’ bitter divorce. So when she attends the festival of Tanabata, her wish is simple: proof that love is real and can last.
Emma thinks little of her wish…until she finds a note from someone claiming to be her greatest love writing to her from the future. It has to be a prank, right? But as the notes pour in, each revealing secrets only she knows, Emma is forced to accept the impossible: This is really happening. Someone is actually reaching out to her from across time.
But who? Ezra, the musical prodigy who makes her pulse race? Theo, the literal boy next door who’s known her since childhood? Or Colin, the overly confident, overly handsome, overly rich kid she meets while cleaning his mega-mansion?
As Emma races to uncover the identity of the letter writer, she’ll discover that love is more than real—it’s the most powerful force in the universe. And it’s been waiting for her all along.

About the book
The last survivors. The last chance. The last leap through time…
Finalist, 2025 Hoffer Book Awards Grand Prize
Rated 9.5/10 by Publishers Weekly's BookLife Prize in Fiction
For fans of The Murderbot Diaries, The Martian, and Dark Matter comes a fast-paced, emotional journey through love, loss, and redemption set in a future collapsing under its own weight.
Fifty years from now, the last humans hide beneath glass domes while swarms of microdrones tear at the last defenses of a drowning world. Inside Eden-17, a dying scientist and her lifelong love cling to hope—and each other—while a sarcastic, duct-taped AI named Madders keeps the biodome online.
But time is running out. Power is fading. Options are gone. They face one impossible choice: shut down everything—including Madders—to send one of them back in time, leaving the other behind to face the end.
Alone.
Diego refuses to go. But Isabel knows what’s coming. He has to do it. For her.
Thirty-five years earlier, Isabel’s life is unraveling. Her marriage is over. Her future is empty. Then a stranger shows up with a haunted gaze and a warning she doesn’t want to hear. He's not supposed to talk to her, but he knows what’s coming. And what she does next will determine everything.
As the multiverse buckles under the weight of its own contradictions, a far-future Madders peers across timelines: at a physicist chasing the ghost of a time machine, a woman whose quiet choices could ignite revolution, and a man bound to her by love, grief, and time itself.
Rewrite the past without consequences? Go ahead. Try.
Lyrical and unflinching, Hive is the award-winning first book in the Madders in Time series—an emotional, character-driven sci-fi thriller where time travel isn’t a gimmick but a reckoning. Follow the tenuous thread woven through fractured timelines, fragile hearts, and white-knuckle suspense. Step into a world where time is both the enemy and the only option.
Hope’s a hell of a thing to weaponize—especially when it’s all you have left.

Remnant Population

Our take
When her colony is evacuated, elderly settler Ofelia refuses to leave the planet she calls home.

Choose your retailer
About the book
Finalist for the Hugo Award • “Ofelia—tough, kind, wise and unwise, fond of food, tired of foolish people—is one of the most probable heroines science fiction has ever known.”—Ursula K. Le Guin
For forty years, Colony 3245.12 has been Ofelia’s home. On this planet far away in space and time from the world of her youth, she has lived and loved, weathered the death of her husband, raised her one surviving child, lovingly tended her garden, and grown placidly old. And it is here that she fully expects to finish out her days—until the shifting corporate fortunes of the Sims Bancorp Company dictates that Colony 3245.12 is to be disbanded, its residents shipped off, deep in cryo-sleep, to somewhere new and strange and not of their choosing. But while her fellow colonists grudgingly anticipate a difficult readjustment on some distant world, Ofelia savors the promise of a golden opportunity. Not starting over in the hurly-burly of a new community . . . but closing out her life in blissful solitude, in the place she has no intention of leaving. A population of one.
With everything she needs to sustain her, and her independent spirit to buoy her, Ofelia actually does start life over–for the first time on her own terms: free of the demands, the judgments, and the petty tyrannies of others. But when a reconnaissance ship returns to her idyllic domain, and its crew is mysteriously slaughtered, Ofelia realizes she is not the sole inhabitant of her paradise after all. And, when the inevitable time of first contact finally arrives, she will find her life changed yet again—in ways she could never have imagined. . . .

About the book
Pair up or be Tithed!
Two things are ever certain in Ironcross: the beasts outside the wall and the Tithe.
When Senna Rhys turns eighteen, she must go through the Tithe, a rite of passage to adulthood and a selection process that claims ten souls for the treaty with the wall. The unpaired are chosen first—securing the next generation to supply the Tithe is the foundation of Ironcross’ survival.
There’s Gabriel, the gorgeous boy next door with blue, blue eyes. He’s been my best friend since forever. He’s the keeper of my heart.
There’s Kane, arrogant and self-assured and darkly beautiful. He wants everything but my heart and has an irritating habit of catching me when I fall.
There’s Ironcross. The wall that keeps the beasts out. The fear that keeps us in. The Alders who rule with ruthless clarity.
Above all else, there’s the Tithe. The pact and sacrifice and pairings that bind our world.
Tithe is a post-apocalyptic romance and adventure with some disturbing themes set in a dark, dystopian world.

They tell me he's dangerous. His memories tell me he's not.
Someone is lying, and it's my job to figure out who.

She’s the best chance the country has at stopping the Seers—the terrorist organization using the weather as a weapon.

Pretty much every girl in Port Gibson likes the same two guys, and Ruby knows them both. Wesley, the charismatic son of the town Mayor who's being groomed to step into his dad's job, and Sam, the ripped but terrifying second-in-command to the town's Security Chief. But only Wesley's graduating with Ruby, and if he shows up, she's determined to finally seize her chance to kiss her long time crush.
When things go sideways, endangering her dear Wesley's life, there's only one person Ruby can ask for help, no matter how scary and enigmatic he is: Samuel Roth. Can Ruby convince Sam to risk his life to save Wesley's? And can Ruby navigate the post-apocalyptic world in time to save her crush, or will the long forgotten past come back to claim its due?

About the book

Spaceships aren’t programmed to seek revenge—but for Dracula, Demeter will make an exception.
Demeter just wants to do her job: shuttling humans between Earth and Alpha Centauri. Unfortunately, her passengers keep dying—and not from equipment failures, as her AI medical system, Steward, would have her believe. These are paranormal murders, and they began when one nasty, ancient vampire decided to board Demeter and kill all her humans.
To keep from getting decommissioned, Demeter must join forces with her own team of monsters: A werewolf. An engineer built from the dead. A pharaoh with otherworldly powers. A vampire with a grudge. A fleet of cheerful spider drones. Together, this motley crew will face down the ultimate evil—Dracula.
The queer love child of pulp horror and classic sci-fi, Of Monsters and Mainframes is a dazzling, heartfelt odyssey that probes what it means to be one of society’s monsters—and explores the many types of friendship that make us human.
