About the book
A centuries-long mission to reach a mysterious star unfolds through a series of vignettes across generations in this "spectacular epic" sci-fi novel (Kirkus, starred review).
In 2088, humankind is finally able to explore beyond Earth's solar system. The interstellar missions will depend on cloning technology that allows a single crew to replicate itself across eons, and astrophysicist Reggie Straifer knows exactly where to send them. Having discovered an anomalous star that appears to defy the laws of physics, he proposes a deep-space mission to determine if the star is a natural phenomenon, or something manufactured.
Reggie himself is among the hundreds of elite experts cloned for the convoy. But a clone is not an exact copy, and each new generation has its own quirks, desires, and neuroses. As the centuries fly by, the society living aboard the nine ships changes and evolves, but their mission remains the same: to reach Reggie's mysterious star and explore its origins—and implications.
A mosaic novel of discovery, Noumenon—in a series of vignettes—follows the men and women, and even the AI, as they are born again and again into a thousand new lives. With the stars their home and the unknown their destination, they are on an odyssey to understand what lies beyond the limits of human knowledge and imagination.

About the book
Beneath the gaze of the gods, the mighty armies of Greece and Troy met in fierce and glorious combat, scrupulously following the text set forth in Homer's timeless narrative. But that was before twenty-first-century scholar Thomas Hockenberry stirred the bloody brew, causing an enraged Achilles to join forces with his archenemy Hector and turn his murderous wrath on Zeus and the entire pantheon of divine manipulators; before the swift and terrible mechanical creatures that catered for centuries to the pitiful idle remnants of Earth's human race began massing in the millions, to exterminate rather than serve.
And now all bets are off.

About the book
From Wall Street Journal bestselling author Joe Hart.
A mysterious worldwide epidemic reduces the birthrate of female infants from 50 percent to less than 1 percent. Medical science and governments around the world scramble in an effort to solve the problem, but twenty-five years later there is no cure, and an entire generation grows up with a population of fewer than a thousand women.
Zoey and some of the surviving young women are housed in a scientific research compound dedicated to determining the cause. For two decades, she’s been isolated from her family, treated as a test subject, and locked away—told only that the virus has wiped out the rest of the world’s population.
Captivity is the only life Zoey has ever known, and escaping her heavily armed captors is no easy task, but she’s determined to leave before she is subjected to the next round of tests…a program that no other woman has ever returned from. Even if she’s successful, Zoey has no idea what she’ll encounter in the strange new world beyond the facility’s walls. Winning her freedom will take brutality she never imagined she possessed, as well as all her strength and cunning—but Zoey is ready for war.

About the book
From one of genre fiction’s most original and revolutionary voices comes a space opera adventure like no other. Sometimes the fate of entire worlds can be decided by a woman with nothing to lose, and the smartest gun in the multiverse in her hand . . .
“The production of a brilliant imagination . . . His best novel yet.”—SFX
This is the story of Bess - or Dog-Bitch Bess as she came to be known. It's the story of the gun she carried, whose name was Wakeful Slim. It's the story of the dead man who carried that gun before her and left a piece of himself inside it. And it's the tale of how she turned from teacher, to renegade, and ultimately to hero.
This is also the tale of the last violent engagements in an inter-dimensional war - one of the most brutal the multiverse had ever seen.
This is how Bess learned the truth about her world. Came to it the hard way, through pain and loss and the reckless spilling of blood, and carried it with her like a brand on her soul. And once she knew it - knew for sure how badly she'd been used - she had no option but to do something about it.
Discover this thrilling standalone science fiction adventure from the million-copy bestselling M. R. Carey, author of The Girl With All the Gifts and the Philip K. Dick Award-shortlisted Infinity Gate (a New York Times Best Science Fiction and Fantasy Book of the Year).

Paradise-1 was supposed to be humanity’s fresh start.
Paradise-1
Horror · Sci-Fi · Space Colonization
Our take
Paradise-1 was supposed to be humanity’s fresh start. Instead, it went silent. When Firewatch inspector Alexandra Petrova is sent to investigate the missing deep-space colony, she expects equipment failure or human error. What she finds is far worse. A tense, claustrophobic blend of sci-fi and horror where exploration turns into survival and every unanswered question makes things more dangerous.
Choose your retailer
About the book
An electric blend of sci-fi and horror, Paradise-1 begins a terrifying new trilogy of exploration and survival in deep space from Arthur C. Clarke Award-nominated author David Wellington.
"A superior space thriller that never flags....Readers will be on the edge of their seats." —Publishers Weekly (starred review)
Paradise-1. Earth’s first deep space colony. For thousands of people, it was an opportunity for a new life. Until it went dark.
No communication has been received from the colony for months. And it falls to Firewatch inspector Alexandra Petrova and the crew of the Artemis to investigate.
What they find is more horrifying than anything they could have imagined.

Choose your retailer
About the book
War rages between the stars. A ruthless empire crushes all resistance. And one ex-soldier will decide the fate of humanity…
The Paragon empire reduces cities to dust and devastates entire planets. Independent star systems fall one by one… until none remain. Fear keeps the population obedient, but rebels and outlaws hide in the shadows.
After decades of fighting, Lax VanDunn is free. Sold to the Paragon military as a child and shaped into a perfect soldier, war is the only life he’s ever known. When he’s released from the army at last, he swears he’s never going back.
Now, Lax works as a salvager, raiding abandoned spacecraft. When an ancient warship is discovered floating in deep space, Lax realizes it contains a priceless secret that could shatter the Paragon’s grip on the galaxy.
Lax never wanted to be a hero. But the Paragon took everything from him—and now he has a chance to strike back. Can he plan an impossible heist, and lead an inexperienced crew through the ship’s lethal defences? Or will the Paragon snatch away his prize—and humanity’s last chance of freedom?
An absolutely thrilling science-fiction adventure of tension, intrigue and hard-hitting action, Starship Salvager is perfect for fans of James S.A. Corey, Marko Kloos and Craig Alanson.
