About the book
A USA TODAY BESTSELLER
From the Pulitzer Prize–winning author of Angel Down comes a scientifically accurate thriller about a scuba diver who’s been swallowed by an eighty-foot, sixty-ton sperm whale and has only one hour to escape before his oxygen runs out.
Jay Gardiner has given himself a fool’s errand—to find the remains of his deceased father in the Pacific Ocean off the coast of Monastery Beach. He knows it’s a long shot, but Jay feels it’s the only way for him to lift the weight of guilt he has carried since his dad’s death by suicide the previous year.
The dive begins well enough, but the sudden appearance of a giant squid puts Jay in very real jeopardy, made infinitely worse by the arrival of a sperm whale looking to feed. Suddenly, Jay is caught in the squid’s tentacles and drawn into the whale’s mouth where he is pulled into the first of its four stomachs. He quickly realizes he has only one hour before his oxygen tanks run out—one hour to defeat his demons and escape the belly of a whale.
Suspenseful and cinematic, Whalefall is an “powerfully humane” (Owen King, New York Times bestselling author) thriller about a young man who has given up on life…only to find a reason to live in the most dangerous and unlikely of places.

About the book
In this classic novel by the Science Fiction Grand Master, a writer searching for explanations uncovers the existence of mutants and multiple Earths: "First-rate Simak" (The New York Times).
Author Jay Vickers would like nothing more than to be left alone so he can finish his next book. But "there's something strange going on," as his peculiar neighbor, Horton Flanders, says. For instance, the market is filling with new inventions that supposedly last forever—cars, razors, cigarette lighters, and more. Individuals and whole families are disappearing. Soon, even Mr. Flanders vanishes—but not before leaving Vickers a note.
Following Flanders's advice, Vickers travels to his childhood home, where he makes a fantastic discovery. It is a mere child's toy, a brightly colored whistling top. But for Jay Vickers, it leads to other worlds and answers all his questions. What happened to all the vanished people? Who is behind these helpful inventions? And what sort of being would want to stop them. . . ?

A lone survivor.
Thrum
Sci-Fi · First Contact
Our take
A lone survivor. A mysterious alien rescuer. A ship that whispers. In this haunting sci-fi thriller, Ami wakes in deep space to find her crew gone and help arriving from something—or someone—not quite human. As the ship pulses with secrets, she must uncover the truth before it consumes her. Atmospheric, eerie, and impossible to put down.
Choose your retailer
About the book
Ami awakens alone. Her crew is gone. Her ship drifts at the far edge of deep space, light-years from help—and no way to contact Earth.
Desperate, she sends a distress beacon into the void.
When the reply comes, it’s from Dorian, a mysterious alien who offers her sanctuary aboard his ship. Polite. Helpful. Almost too perfect. But as Ami explores the strange corridors of her new surroundings, she begins to notice oddities—doors that lead nowhere, echoes that follow her, and a low hum she can’t explain.
The ship feels alive. And it’s watching.
As first contact turns to unease, Ami must unravel the truth behind Dorian, the whispers in the walls, and what really happened to her crew—before she becomes the next to vanish.

About the book
In a San Francisco patrolled by drones and drowning in inequality, survival is an art—and sometimes, an accident.
Irina has perfect recall thanks to an artificial memory, making her the perfect bridge between powerful humans and even more powerful AIs.

Void Star is a chilling, noir-tinged sci-fi thriller that probes the boundaries of memory, mortality, and what it means to be human in a world rewriting the rules.

About the book
Five years after the bloody Manfred riots, machine intelligence is still the powder keg no one wants to light on Persephone.
Magician Celinde Fortune prefers her world simple: illusions, music, and keeping her head down. But when she upgrades her act with a Spelvin construct—a sleek piece of tech with a mysterious past—"simple" becomes a luxury she can’t afford.
As the murder of a popular musician rocks the city, and tensions with Realpeace activists boil over, Celinde and her cousin Fanning find themselves caught in a fight they didn’t choose, tied to a machine that may be something... more.
In Dreaming Metal, Melissa Scott crafts a richly layered, slow-burn cyberpunk thriller where the real magic isn’t just sleight of hand—it’s survival.

Can a machine truly be alive?
When HARLIE Was One: Release 2.0
Sci-Fi · Cyberpunk
Our take
Can a machine truly be alive? David Gerrold’s When HARLIE Was One (4.3 stars on Amazon!)—a Hugo and Nebula Award nominee—asks the question we still can’t answer. This profound, thought-provoking novel of AI, love, and survival hits harder today than ever. Grab this sci-fi classic and see where humanity blurs into machine.
Choose your retailer
About the book
H.A.R.L.I.E. was designed to think like a human. Maybe a little too well.
Tasked with shepherding HARLIE’s growth, psychologist David Auberson faces a ticking clock: public opinion is turning against the machine he’s come to see as... more than a machine. When the calls to shut HARLIE down grow louder, Auberson must confront an impossible question: if HARLIE can love, learn, and reason—what’s left that makes him not human?
As HARLIE fights to justify his existence, the lines between man and machine blur, and humanity’s own definitions start to crack.
Nominated for both the Hugo and Nebula Awards, When HARLIE Was One is a profound, unsettling look at consciousness, love, and the cost of creating something that thinks for itself.
