About the book
Once every year, Scoutmaster Tim Riggs leads a troop of boys into the Canadian wilderness for a weekend camping trip—a tradition as comforting and reliable as a good ghost story around a roaring bonfire. But when an unexpected intruder stumbles upon their campsite—shockingly thin, disturbingly pale, and voraciously hungry—Tim and the boys are exposed to something far more frightening than any tale of terror. The human carrier of a bioengineered nightmare. A horror that spreads faster than fear. A harrowing struggle for survival with no escape from the elements, the infected…or one another.

About the book
Now featuring never-before-seen material, the “brilliantly realized” (The New York Times Book Review) breakthrough novel from visionary author Neal Stephenson, a modern classic that predicted the metaverse and inspired generations of Silicon Valley innovators
Hiro lives in a Los Angeles where franchises line the freeway as far as the eye can see. The only relief from the sea of logos is within the autonomous city-states, where law-abiding citizens don’t dare leave their mansions.
Hiro delivers pizza to the mansions for a living, defending his pies from marauders when necessary with a matched set of samurai swords. His home is a shared 20 X 30 U-Stor-It. He spends most of his time goggled in to the Metaverse, where his avatar is legendary.
But in the club known as The Black Sun, his fellow hackers are being felled by a weird new drug called Snow Crash that reduces them to nothing more than a jittering cloud of bad digital karma (and IRL, a vegetative state).
Investigating the Infocalypse leads Hiro all the way back to the beginning of language itself, with roots in an ancient Sumerian priesthood. He’ll be joined by Y.T., a fearless teenaged skateboard courier. Together, they must race to stop a shadowy virtual villain hell-bent on world domination.

About the book
The first novel in Isaac Asimov’s classic science-fiction masterpiece, the Foundation series
THE EPIC SAGA THAT INSPIRED THE APPLE TV+ SERIES FOUNDATION • Nominated as one of America’s best-loved novels by PBS’s The Great American Read
For twelve thousand years the Galactic Empire has ruled supreme. Now it is dying. But only Hari Seldon, creator of the revolutionary science of psychohistory, can see into the future—to a dark age of ignorance, barbarism, and warfare that will last thirty thousand years. To preserve knowledge and save humankind, Seldon gathers the best minds in the Empire—both scientists and scholars—and brings them to a bleak planet at the edge of the galaxy to serve as a beacon of hope for future generations. He calls his sanctuary the Foundation.
The Foundation novels of Isaac Asimov are among the most influential in the history of science fiction, celebrated for their unique blend of breathtaking action, daring ideas, and extensive worldbuilding. In Foundation, Asimov has written a timely and timeless novel of the best—and worst—that lies in humanity, and the power of even a few courageous souls to shine a light in a universe of darkness.

#1 NEW YORK TIMES BESTSELLER • Now a major motion picture starring Ryan Gosling, directed by Phil Lord and Christopher Miller, with a screenplay by Drew Goddard

HUGO AWARD FINALIST • NEW YORK TIMES READER PICK: 100 BEST BOOKS OF THE 21ST CENTURY • ONE OF THE YEAR’S BEST BOOKS: Parade, Newsweek, New York Public Library, Polygon, Shelf Awareness, She Reads, Kirkus Reviews, Library Journal
Ryland Grace is the sole survivor on a desperate, last-chance mission—and if he fails, humanity and the earth itself will perish.
Except that right now, he doesn’t know that. He can’t even remember his own name, let alone the nature of his assignment or how to complete it.
All he knows is that he’s been asleep for a very, very long time. And he’s just been awakened to find himself millions of miles from home, with nothing but two corpses for company.
His crewmates dead, his memories fuzzily returning, Ryland realizes that an impossible task now confronts him. Hurtling through space on this tiny ship, it’s up to him to puzzle out an impossible scientific mystery—and conquer an extinction-level threat to our species.
And with the clock ticking down and the nearest human being light-years away, he’s got to do it all alone.
Or does he?
Hailed by USA Today as “an epic story of redemption, discovery, and cool speculative sci-fi,” Project Hail Mary is an irresistible interstellar adventure as only Andy Weir could deliver.

Their vessel is controlled by HAL 9000, an artificially intelligent supercomputer capable of the highest level of cognitive functioning that rivals—and perhaps threatens—the human mind.

About the book
Death-row inmates are used for a lethal mining operation—but one is innocent—in this science fiction novel by a #1 New York Times–bestselling author.
Only the recently dead can helm the "deadman switch" to pilot a ship through the Cloud, a mysterious solar entity that shields the Solitaire solar system and its valuable heavy metals. Two convicted murderers are routinely sacrificed for this task—one to enter the system, one to exit. Gilead Raca Benedar is a Watcher, employed by the wealthy head of an intergalactic mining company as a human lie detector of sorts. When Benedar is sent to Solitaire, with its metal-rich moons, to assist with the acquisition of its valuable mining rights, he and the crew are able to make it to Solitaire safely, and all goes well. That is, until Benedar's Watcher powers show him that the second convict they are traveling with—the one meant to helm the deadman switch on their return journey—is innocent.

J.G. Ballard’s The Drowned World presents a vivid and unsettling vision of 2145, where melting ice caps have turned London into a tropical wilderness.
The Drowned World
Sci-Fi
Our take
J.G. Ballard’s The Drowned World presents a vivid and unsettling vision of 2145, where melting ice caps have turned London into a tropical wilderness. Biologist Dr. Robert Kearns faces a perilous landscape dominated by giant lizards and insects. Blending psychological depth with thrilling adventure, Ballard’s novel is a striking exploration of nature’s resurgence and humanity’s fragility.
Choose your retailer
About the book
First published in 1962, J.G.Ballard’s mesmerizing and ferociously imaginative novel not only gained him widespread critical acclaim but also established his reputation as one of the finest writers of a generation. The Drowned World imagines a terrifying world in which global warming has melted the ice caps and primordial jungle shave overrun a tropical London. Set during the year 2145, this novel follows biologist Dr. Robert Kearns and his team of scientists as they confront a city scape in which nature is on the rampage and giant lizards, dragonflies, and insects fiercely compete for domination. Both an unmatched biological mystery and a brilliant retelling of Heart of Darkness—complete with a mad white hunter and his hordes of native soldiers—this “powerful and beautifully clear” (Brian Aldiss) work becomes a thrilling adventure with “an oppressive power reminiscent of Conrad” (Kingsley Amis).

The Invisible Library
Fantasy · Sci-Fi
Our take
Irene works as a spy for the mysterious Library, collecting rare books from alternate realities. Sent to a chaotic version of London with her secretive assistant, Kai, she’s tasked with retrieving a powerful tome—only to find it stolen. With supernatural forces and hidden agendas closing in, Irene must navigate a perilous world where reality itself hangs in the balance.
Choose your retailer
About the book
One thing any Librarian will tell you: the truth is much stranger than fiction...
Irene is a professional spy for the mysterious Library, a shadowy organization that collects important works of fiction from all of the different realities. Most recently, she and her enigmatic assistant Kai have been sent to an alternative London. Their mission: Retrieve a particularly dangerous book. The problem: By the time they arrive, it's already been stolen.
London's underground factions are prepared to fight to the death to find the tome before Irene and Kai do, a problem compounded by the fact that this world is chaos-infested—the laws of nature bent to allow supernatural creatures and unpredictable magic to run rampant. To make matters worse, Kai is hiding something—secrets that could be just as volatile as the chaos-filled world itself.
Now Irene is caught in a puzzling web of deadly danger, conflicting clues, and sinister secret societies. And failure is not an option—because it isn’t just Irene’s reputation at stake, it’s the nature of reality itself...

About the book
A destructive entity hiding within a dark nebula threatens the future of the inhabitants of the Great Ship in this space opera sequel to Marrow.
"This literary SF novel works at all levels, from the big action sequences and mind-expanding concepts to the quiet, reflective moments." —Publishers Weekly (starred review)
In The Well of Stars, Hugo award-nominated author Robert Reed has written a stunning sequel to his acclaimed novel Marrow. The Great Ship, so vast that it contains within its depths a planet that lay undiscovered for generations, has cruised through the universe for untold billions of years. After a disastrous exploration of the planet, Marrow, the Ship's captains face an increasingly restive population aboard their mammoth vessel.
And now, compounding the captains' troubles, the Ship is heading on an irreversible course straight for the Ink Well, a dark, opaque nebula. Washen and Pamir, the captains who saved Marrow from utter destruction, send Mere, whose uncanny ability to adapt to and understand other cultures makes her the only one for the job, to investigate the nebula before they plunge blindly in. While Mere is away, Pamir discovers in the Ink Well the presence of a god-like entity with powers so potentially destructive that it might destroy the ship and its millions.
Faced with an entity that might prevent the Ship from ever leaving the Ink Well, the Ship's only hope now rests in the ingenuity of the vast crew . . . and with Mere, who has not contacted them since she left the Ship . . .
With the excitement of epic science fiction adventure set against a universe full of wonders, the odyssey of the Ship and its captains will capture the hearts of science fiction readers.
