About the book
NOW A MAJOR MOTION PICTURE
"On every level, Cold Storage is pure, unadulterated entertainment." —Douglas Preston, The New York Times Book Review
For fans of The Martian, Dark Matter, and Before the Fall comes an astonishing debut thriller by the screenwriter of Jurassic Park: a wild and terrifying bioterrorism adventure about three strangers who must work together to contain a highly contagious, deadly organism that could destroy all of humanity.
They thought it was contained. They were wrong.
When Pentagon bioterror operative Roberto Diaz was sent to investigate a suspected biochemical attack, he found something far worse: a highly mutative organism capable of extinction-level destruction. He contained it and buried it in cold storage deep beneath a little-used military repository.
Now, after decades of festering in a forgotten sub-basement, the specimen has found its way out and is on a lethal feeding frenzy. Only Diaz knows how to stop it.
He races across the country to help two unwitting security guards—one an ex-con, the other a single mother. Over one harrowing night, the unlikely trio must figure out how to quarantine this horror again. All they have is luck, fearlessness, and a mordant sense of humor. Will that be enough to save all of humanity?

About the book
From Michael Crichton, the #1 bestselling author of Jurassic Park and The Andromeda Strain, comes a devilishly clever, breathless tale of a new world where nothing is what it seems, and genetic ownership shatters our assumptions.
Welcome to our genetic world.
Fast, furious, and out of control.
This is not the world of the future—it's the world right now.
Is a loved one missing some body parts? Are blonds becoming extinct? Is everyone at your dinner table of the same species? Humans and chimpanzees differ in only four hundred genes; is that why a chimp fetus resembles a human being? And should that worry us? There's a new genetic cure for drug addiction—is it worse than the disease?
We live in a time of momentous scientific leaps, a time when it's possible to sell our eggs and sperm online for thousands of dollars and to test our spouses for genetic maladies. We live in a time when one-fifth of all our genes are owned by someone else—and an unsuspecting person and his family can be pursued cross-country because they happen to have certain valuable genes within their chromosomes....
The future is closer than you think.

Peace
Dystopian · Fantasy · Sci-Fi
Our take
Called “a tricky, evil, deep, and remarkable novel” by Neil Gaiman, Peace follows elderly Alden Dennis Weer as he recounts his life in a small Midwestern town, with his memories reshaping time and reality. Best for readers who like intricate literary fantasy about memory, imagination, and death.
Choose your retailer
About the book
Hailed as "one of the literary giants of SF" by the Denver Post, Gene Wolfe has repeatedly won the field's highest honors, including the Nebula, the Hugo, and the World Fantasy awards.
Peace is Gene Wolfe's first full-length novel, a work that shows the genius that later flourished in such acclaimed works as The Fifth Head of Cerberus and The Book of The New Sun.
Originally published in 1975, Peace is a spellbinding, brilliant tour de force of the imagination. The melancholy memoir of Alden Dennis Weer, an embittered old man living out his last days in a small midwestern town, the novel reveals a miraculous dimension as the narrative unfolds. For Weer's imagination has the power to obliterate time and reshape reality, transcending even death itself. Powerfully moving and uncompromisingly honest, Peace ranks alongside the finest literary works of our time.

When an outline for Variable Star was found among Robert A. Heinlein's papers, Spider Robinson was commissioned to complete the novel. The result is a thrilling new work of science fiction from two of the genre's greatest minds.

8 HOURS TO STOP AN EXPLOSION...8 HOURS TO FALL IN LOVE.
From the New York Times bestselling co-author of Illuminae and Aurora Rising comes a high-stakes, high-chemistry, sci-fi romp about a stowaway girl and the richest boy in the galaxy, racing the clock to outwit a gang of mercenaries.
It’s 2067, and the Graves family has transformed Mars from a lifeless rock into a chaotic patch of settlements. You can buy a one-way ticket to a new life--if you're rich.
Enter Hunter Graves, the handsome, ambitious grandson of the man who settled Mars. With spectacularly bad timing, Hunter arrives at the United Nations base just as an emergency evacuation sends everyone scurrying for safety. Except he’s left behind. Uh-oh.
Also stranded: Cleo, a sharp-tonged stowaway with no intention of dying today, and even less patience for overconfident trust fund boys. But the enemy of your enemy might just help you survive, so here we are.
It turns out the evacuation is just a cover for the mercenaries who come next, and the plan to blow up the base--and every trace of their crime--in eight hours.
Now, Hunter and Cleo have one shot to stop the explosion, escape alive, and deal with the inconvenient fact that they're falling for each other.
The clock is ticking.

About the book
From #1 New York Times bestselling author Brandon Sanderson and Janci Patterson comes the first book in a new, high-flying trilogy featuring the legendary Skyward Flight as they undertake a deadly intergalactic mission to explore a mysterious alien world.
After decades of war against alien oppressors, the humans of the Defiant Defense Force are finally free. Yet for Arturo Mendez, leader of Skyward Flight, freedom isn’t what he thought it would be.
His first postwar assignment seems simple: The DDF has found evidence of other settlements of humans who were isolated during their long war against the aliens, and Arturo and his flight of pilots are to escort a team of diplomats as they attempt to make contact. It’s an easy mission—get in, guard the diplomats, and get out.
But no element of this mission turns out to be simple. Blightfall is inhospitable, surrounded by mysterious debris and covered in giant, invasive forests that have swallowed most of the planet. Upon arrival, Arturo’s team is attacked, and it quickly becomes clear that this human settlement isn’t what it appears to be.
Now trapped in an unfamiliar world and unsure who to trust, Arturo and his team must find allies and uncover long-buried secrets if they hope to escape and return home.
