About the book
From a New York Times bestselling and Hugo award-winning author comes a modern masterwork of science fiction, introducing a captain, his crew, and a detective as they unravel a horrifying solar system wide conspiracy that begins with a single missing girl. Now a Prime Original series.
Humanity has colonized the solar system—Mars, the Moon, the Asteroid Belt and beyond—but the stars are still out of our reach.
Jim Holden is XO of an ice miner making runs from the rings of Saturn to the mining stations of the Belt. When he and his crew stumble upon a derelict ship, the Scopuli, they find themselves in possession of a secret they never wanted. A secret that someone is willing to kill for—and kill on a scale unfathomable to Jim and his crew. War is brewing in the system unless he can find out who left the ship and why.
Detective Miller is looking for a girl. One girl in a system of billions, but her parents have money and money talks. When the trail leads him to the Scopuli and rebel sympathizer Holden, he realizes that this girl may be the key to everything.
Holden and Miller must thread the needle between the Earth government, the Outer Planet revolutionaries, and secretive corporations—and the odds are against them. But out in the Belt, the rules are different, and one small ship can change the fate of the universe.
"Interplanetary adventure the way it ought to be written." —George R. R. Martin

About the book
Beckett Gray thinks the world just ended. His car won’t start, his phone is dead, and the forest around the Appalachian Trail feels eerily quiet. An EMP? That’s the only explanation.
Until it isn’t.
Beckett and a handful of fellow hikers soon realize the truth is far stranger—and far more terrifying. They haven’t lost power. They’ve lost time. Five hundred years, to be exact.
Now stranded in a brutal, pre-modern world, they must fight to survive in a time that wants them dead. No shelter. No tech. No welcome. Just raw nature, hostile locals, and a past that refuses to let them go.
Is it still survival if history itself is trying to kill you?

Our take
Humanity’s first interstellar mission was meant to bring peace—not bodies.

Choose your retailer
About the book
In 2069, Earth’s last shot at peace is one spaceship—and one crew—away from unraveling.
Leif Grettison wasn’t supposed to be here. He won the final seat on humanity’s first interstellar mission in a global lottery. But he’s no average joe—he’s a battle-hardened paramedic, lab tech, and former Army Ranger. Now he’s the unofficial muscle aboard a ship full of fragile alliances and national grudges, barreling toward an alien world no one really understands.
The journey spans fourteen Earth years. The dangers? Immeasurable.
When systems fail, tensions spike, and crew members start dying, Leif must become more than a handyman—he must be humanity’s last line of defense against the unknown.
Because space doesn’t care how well you planned. And out here, there’s no calling for backup.

Volcanoes.
Devolution
Horror · Sci-Fi · Travis' Picks · Post-Apocalyptic
Our take
Volcanoes. Isolation. Bigfoot. Devolution by Max Brooks (World War Z) is the survival horror thriller you didn’t know you needed. Told through recovered journals and dark research, this 4.5-star bestseller explores the bloody truth behind a forgotten massacre in the Washington wilderness. Finalist for the Locus Award. Click now to discover why Bigfoot is not the cuddly cryptid you imagined.
Choose your retailer
About the book
Mount Rainier erupted. Then something far worse came down from the mountains.
Devolution is Max Brooks’ gripping, genre-bending Bigfoot horror novel that blends survival thriller, investigative journalism, and blood-soaked suspense. Told through the recovered journal of Kate Holland and paired with chilling research, the story of Greenloop—a high-tech eco-community turned massacre site—unfolds in terrifying detail.
Trapped by volcanic devastation and cut off from civilization, the residents of Greenloop face something far more primal than isolation: a brutal tribe of Sasquatch with a taste for human flesh.
From the author of World War Z, Devolution delivers relentless tension, unforgettable characters, and a Bigfoot tale that feels horrifyingly possible.
Believe or don’t. But if Kate’s account is real… you’ll never hike the woods the same way again.

ONE OF THE BEST BOOKS OF THE YEAR—Entertainment Weekly, BuzzFeed, Shelf Awareness
“I live for the dream that my children will be born free,” she says. “That they will be what they like. That they will own the land their father gave them.”
“I live for you,” I say sadly.
Eo kisses my cheek. “Then you must live for more.”
Darrow is a Red, a member of the lowest caste in the color-coded society of the future. Like his fellow Reds, he works all day, believing that he and his people are making the surface of Mars livable for future generations. Yet he toils willingly, trusting that his blood and sweat will one day result in a better world for his children.
But Darrow and his kind have been betrayed. Soon he discovers that humanity reached the surface generations ago. Vast cities and lush wilds spread across the planet. Darrow—and Reds like him—are nothing more than slaves to a decadent ruling class.
Inspired by a longing for justice, and driven by the memory of lost love, Darrow sacrifices everything to infiltrate the legendary Institute, a proving ground for the dominant Gold caste, where the next generation of humanity’s overlords struggle for power. He will be forced to compete for his life and the very future of civilization against the best and most brutal of Society’s ruling class. There, he will stop at nothing to bring down his enemies . . . even if it means he has to become one of them to do so.
