About the book
The New York Times bestselling author of Neuromancer and Agency presents a fast-paced sci-fi thriller that takes a terrifying look into the future.
DON'T MISS THE SERIES—NOW STREAMING EXCLUSIVELY ON PRIME VIDEO!
Flynne Fisher lives down a country road, in a rural America where jobs are scarce, unless you count illegal drug manufacture, which she’s trying to avoid. Her brother Burton lives on money from the Veterans Administration, for neurological damage suffered in the Marines’ elite Haptic Recon unit. Flynne earns what she can by assembling product at the local 3D printshop. She made more as a combat scout in an online game, playing for a rich man, but she’s had to let the shooter games go.
Wilf Netherton lives in London, seventy-some years later, on the far side of decades of slow-motion apocalypse. Things are pretty good now, for the haves, and there aren’t many have-nots left. Wilf, a high-powered publicist and celebrity-minder, fancies himself a romantic misfit, in a society where reaching into the past is just another hobby.
Burton’s been moonlighting online, secretly working security in some game prototype, a virtual world that looks vaguely like London, but a lot weirder. He’s got Flynne taking over shifts, promised her the game’s not a shooter. Still, the crime she witnesses there is plenty bad.
Flynne and Wilf are about to meet one another. Her world will be altered utterly, irrevocably, and Wilf’s, for all its decadence and power, will learn that some of these third-world types from the past can be badass.

About the book
Humanity’s complex relationship with technology spirals out of control in this first book of an all-new series from “the owner of the most powerful imagination in science fiction” (Ken Follett).
“How far ‘space opera’ has come! The Old Masters of sci-fi would admire the scope and sweep of Salvation.”—The Wall Street Journal
In the year 2204, humanity is expanding into the wider galaxy in leaps and bounds. Cutting-edge technology of linked jump gates has rendered most forms of transportation—including starships—virtually obsolete. Every place on Earth, every distant planet humankind has settled, is now merely a step away from any other. All seems wonderful—until a crashed alien spaceship of unknown origin is found on a newly located world eighty-nine light-years from Earth, carrying a cargo as strange as it is horrifying. To assess the potential of the threat, a high-powered team is dispatched to investigate. But one of them may not be all they seem. . . .
Bursting with tension and big ideas, Peter F. Hamilton’s Salvation is the first book of an all-new series that highlights the inventiveness of an author at the top of his game.

Our take
After a mysterious earthquake hits Denver, a scientist descends into a buried military site to prevent disaster. What she uncovers is a lethal biological secret never meant to surface.

About the book
Secrets aren’t the only things that won’t stay buried.
When an earthquake strikes downtown Denver, far from the nearest active fault system, the USGS dispatches Dr. Dayna Raines and an emergency response team to investigate. They discover that the epicenter corresponds to a decommissioned deep injection well once used by the U.S. Army to dispose of chemical weapons, which have eroded the earth and created the unstable cavern system responsible for the seismic activity.
Their mission is to descend into the unknown depths, evaluate the fault zone, and initiate a controlled demolition of the subterranean cavity before another earthquake strikes, causing a mass casualty event. And they’re running out of time.
But military scientists had been experimenting with even deadlier armaments, including a biological organism so lethal that they were forced to bury it two miles down, where no one would ever find it.
Until now.

Our take
Andrew Moriarty’s Imperial Deserter is a sharp, fast-paced space opera full of snappy dialogue, galactic intrigue, and morally gray rogues.

About the book
Kill a man and you're a murderer. Kill a million and you're a statesman. Dirk should have killed more people.
Dirriken Friedel used his aristocratic connections to rescue his troops. He didn’t plan on starting a war or killing them himself. Now he spends his days in jail, waiting for an assassin sent by his dead officers families to end his misery.
When he’s broken out by off-duty marines he has a chance to start over, if he’s worthy. During his ramshackle escape he collects a broken-down trading ship, a bitter former army officer, a genetically altered religious fanatic, a runaway ingenue, a sham engineer, and a murderous femme fatal. Pursed by a fanatical imperial tribune bent on bloody justice, can he keep the crew from killing each other, the ship from exploding, and himself from the bottom of a bottle. Or would it be easier just to give up?
If you like Galactic Empires, honorable enemies, and snappy dialog, this one’s for you.

About the book
Idle immortals, hungry for entertainment, turn their attention to humans in this science fiction novel by the New York Times–bestselling author of Dune.
Immortal aliens had observed Earth for centuries, making and viewing full sensory movies of wars, natural disasters, and horrific human activities . . . all to relieve their boredom. Then they finally became jaded by ordinary, run-of-the-mill tragedies, and found ways to create even more inventive spectacles to keep themselves amused.
But interfering with human activities is forbidden, and by the time Investigator Kelexel arrives to investigate, things are really getting out of hand . . .

About the book
Deep beneath the sands of Egypt, archaeologists uncover something impossible: a mummified body sealed in a tomb, wearing a space suit. Half a world away, Dr. Katherine Shepard and Colonel Devon Peters investigate a crashed UFO and find one of its passengers still alive—and unmistakably human.
Their discoveries link to a truth buried across millennia: aliens have walked among us, shaping Earth’s history from the shadows. Worse, they are still here. A secret war rages between factions older than civilization itself, and humanity is collateral damage.
As Shepard and Peters chase answers through shifting allegiances and hidden agendas, they realize survival depends on unraveling the aliens’ plan before it unravels them. Some revelations can’t be contained. This one could end the world.

An Unkindness of Ghosts
People of Color · Sci-Fi
Our take
Called “intensely thought-provoking,” An Unkindness of Ghosts follows Aster, a lowdeck resident aboard the HSS Matilda, a generation ship structured like the antebellum South, as she confronts oppression, a brutal overseer, and the possibility of civil war, with a 4.4-star rating from more than 1,800 Amazon reviewers.

About the book
An "intensely thought-provoking" science fiction debut from a worthy successor to Octavia Butler (LeVar Burton Reads).
One of Esquire magazine's 50 Best Sci-Fi Books of All Time
Aster has little to offer folks in the way of rebuttal when they call her an ogre and a freak. She's used to the names; she only wishes there was more truth to them. If she was truly a monster, she'd be powerful enough to tear down the walls around her until nothing remained of her world.
Aster lives in the lowdeck slums of the HSS Matilda, a space vessel organized much like the antebellum South. For generations, Matilda has ferried the last of humanity to a mythical Promised Land. On its way, the ship's leaders have imposed harsh moral restrictions and deep indignities on dark-skinned sharecroppers like Aster. Embroiled in a grudge with a brutal overseer, Aster learns there may be a way to improve her lot—if she's willing to sow the seeds of civil war.
"Solomon debuts with a raw distillation of slavery, feudalism, prison, and religion that kicks like rotgut moonshine . . . Stunning." —Publishers Weekly, starred review
"What Solomon achieves with this debut—the sharpness, the depth, the precision—puts me in mind of a syringe full of stars. . . . its only imperfection is that it ended." —NPR
"It's structurally and thematically daring and manages to include a little bit of hope while leveling a devastating critique at racism and fascism." —Los Angeles Times

About the book
Tom Rice thought his first assignment as a graduate student would be straightforward: join a team of archaeologists and dig through the remains of an ancient alien civilization. The High Ones ruled the galaxy millennia ago, and now only fragments of their culture remain—cryptic artifacts scattered across the stars.
When the team uncovers a “message cube” containing living images of the High Ones, everything changes. The footage suggests these beings may not be extinct after all. What began as an academic mission suddenly becomes a dangerous pursuit across the cosmos.
Each discovery leads to new peril, as Tom and his crew hurtle toward answers that could rewrite humanity’s place in the universe. Some relics should be left buried. This one refuses to stay quiet.

About the book
A wreck in space means one thing to Carl Ramsey: opportunity. With the escape pods gone and a distress beacon still flashing, all he has to do is clear out the pirates and claim the salvage. Easy money—at least in theory.
In practice, Carl’s crew is a chaotic mess. His ex-wife pilots the ship, their mechanic is usually drunk, the bodyguard is terrifying, and the resident wizard was kicked out of the Convocation. On a good day, they might function like a proper crew. On most days, Carl just hopes they do not kill each other before payday.
Fuel is expensive, jobs are dangerous, and the surprises are never good. Welcome to the Black Ocean, where survival takes guts, luck, and the occasional miracle.

About the book
In the distant future, humanity is a minor player in a galaxy dominated by ancient civilizations. The Ildirans rule with their Mage-Imperator. The Klikiss have vanished, leaving behind mysterious artifacts and strange technology. Humans, new to the stars, are still struggling to prove themselves.

Caught in the crossfire of gods and empires, humanity may find itself at the bottom of the food chain. Kevin J. Anderson launches a galaxy-spanning saga of war, politics, and survival.
