On an island built from the world’s electronic waste, survival depends on enduring the systems that profit from human ruin.
Waste Tide
Dystopian · Hard Sci-Fi · Techno-Thriller
Our take
On an island built from the world’s electronic waste, survival depends on enduring the systems that profit from human ruin. Waste Tide follows Mimi, a migrant waste worker caught in a violent struggle between gangs, investors, and revolutionaries in a near-future China poisoned by capitalism and control. This eco-tech thriller blends class conflict, environmental collapse, and sharp social vision into a story that feels both harrowing and urgently real.

About the book
A Locus Award Finalist for Best First Novel. "An accomplished eco-techno-thriller with heart and soul as well as brain." —David Mitchell, New York Times-bestselling author of Cloud Atlas
Translated by Ken Liu, who brought Cixin Liu's Hugo Award-winning The Three Body Problem to English-speaking readers.
Mimi is drowning in the world's trash.
She's a waste worker on Silicon Isle, where electronics—from cell phones and laptops to bots and bionic limbs—are sent to be recycled. These amass in towering heaps, polluting every spare inch of land. On this island off the coast of China, the fruits of capitalism and consumer culture come to a toxic end.
Mimi and thousands of migrant waste workers like her are lured to Silicon Isle with the promise of steady work and a better life. They're the lifeblood of the island's economy, but are at the mercy of those in power.
A storm is brewing, between ruthless local gangs, warring for control. Ecoterrorists, set on toppling the status quo. American investors, hungry for profit. And a Chinese-American interpreter, searching for his roots.
As these forces collide, a war erupts—between the rich and the poor; between tradition and modern ambition; between humanity's past and its future.
Mimi, and others like her, must decide if they will remain pawns in this war or change the rules of the game altogether.
"A chilling sci-fi novel about class war and trash in near-future China, and the people the world's economy leaves behind . . . Pressingly relevant." —The Verge
"Thrilling . . . fresh." —The Washington Post
"Viscerally gripping action . . . sheer excellence." —Kirkus Reviews (starred review)

About the book
Reality is coming apart.
Across the world, people are being struck by vivid memories of lives they never lived. It looks like a disease, but there is no infection, no pattern, and no cure. Something deeper is at work. Something that threatens the structure of time itself.
Detective Barry Sutton is chasing the impossible. Neuroscientist Helena Smith is building a device meant to preserve memories. Neither of them is prepared for what they are about to uncover.
As time begins to shift and fracture, Barry and Helena find themselves at the center of a mystery that spans lifetimes. The choices they make could reset everything. Or destroy it.
In Recursion, Blake Crouch delivers a fast-paced, mind-bending thriller about memory, identity, and how far we’ll go to hold on to what matters.

About the book
THE BASIS FOR SILO, NOW A #1 STREAMING SHOW ON APPLE TV
In this second volume in the New York Times best-selling Silo series, Hugh Howey describes the catastrophic events that led to the creation of the silo— and the beginning of the end
In 2007, the Center for Automation in Nanobiotech (CAN) outlined the hardware and software platforms that would one day allow robots smaller than human cells to make medical diagnoses, conduct repairs, and even self-propagate. The technology has an almost limitless capacity for good—but in the wrong hands, it could have an equally boundless capacity for evil.
In the same year, the CBS network re-aired a program about the effects of propranolol on sufferers of extreme trauma. A simple pill, it had been discovered, could wipe out the memory of any traumatic event.
At almost the same moment in humanity’s broad history, mankind discovered the means for bringing about its utter downfall, and the ability to forget it ever happened. With this godlike power at their fingertips, can humanity be trusted to create a new—and better—world? Or is it doomed to bring about its own destruction?

About the book
Dr. Madeleine “Max” Maxwell didn’t expect her new job to involve dodging arrows, running from fire, or trying not to die in the 14th century.
At St Mary’s Institute of Historical Research, historians don’t just read about the past. They go there. Literally. With time-travel pods, questionable safety procedures, and a team of eccentric academics, Max finds herself thrust into history’s biggest disasters.
The mission is simple: observe, document, and don’t change anything. But time has a nasty sense of humor, and history doesn’t like being watched.
From the Cretaceous period to the reign of Richard III, chaos is guaranteed. So is tea.
Just One Damned Thing After Another is wildly clever, gloriously unpredictable, and the unforgettable beginning to a series you didn’t know you needed.

Choose your retailer
About the book
What if the world’s new rulers were superpowered—and evil?
Ten years ago, Steelheart destroyed Chicago, murdered David’s father, and proved that no one with powers—Epics—could be trusted. Now, the city lies in ruins under his tyrannical rule, renamed Newcago, a place where fear is law and resistance is suicide.
But David isn’t afraid. He’s spent a decade studying Epics—especially Steelheart—and he’s discovered something others refuse to believe: the invincible can bleed.
To bring Steelheart down, David must join the Reckoners, a secret group waging war against the Epics. He has the knowledge. They have the firepower. Together, they might have a chance.
But as they close in, David will face questions that challenge everything he believes—because sometimes vengeance isn’t as simple as justice.

About the book
A secret agent aboard a galactic railroad must derail a sinister conspiracy in this "rip-roaring" thriller by the #1 bestselling author of Star Wars: Thrawn (Publishers Weekly).
Hugo Award–Winning Author
The universe is a dangerous place, a fact violently brought home to Frank Compton for perhaps the thousandth time when a stranger delivering a message dies right in front of him. An operative for Western Alliance Intelligence until his whistle-blowing activities got him fired, Compton is now being sought out by the Spiders, the robotic alien beings responsible for the upkeep and operation of the Quadrail transportation system, which connects the galaxy's twelve inhabited empires. The discovery of a sinister plot to use the Quadrail for ill has brought the Spiders to Compton—for only someone possessing the former agent's unique skills can stop the scheme for good.
But when Compton leaves Earth behind—joining forces with Bayta, the Spiders' beautiful, half-human representative aboard the Quadrail—the terrifying scope of a vast, galaxy-wide conspiracy begins to reveal itself. Targeted on all sides by alien assassins of every shape and species, Compton and his enigmatic new partner are suddenly in a race against a clock ticking down to an irreversible doomsday, one in which the galactic night train will derail, carrying all members of humanity screaming to their deaths.
The first in the Quadrail series from the Hugo Award–winning author of Blackcollar and many New York Times–bestselling Star Wars novels, Night Train to Rigel is an action-packed "great read" (Booklist).

In this classic science fiction novel, intelligent dogs inherit Earth after humans abandon the cities, leave for the stars, and fade into legend.

About the book
This award-winning science fiction classic explores a far-future world inhabited by intelligent canines who pass down the tales of their human forefathers.
Thousands of years have passed since humankind abandoned the city—first for the countryside, then for the stars, and ultimately for oblivion—leaving their most loyal animal companions alone on Earth. Granted the power of speech centuries earlier by the revered Bruce Webster, the intelligent, pacifist dogs are the last keepers of human history, raising their pups with bedtime stories, passed down through generations, of the lost "websters" who gave them so much but will never return.
With the aid of Jenkins, an ageless service robot, the dogs live in a world of harmony and peace. But they now face serious threats from their own and other dimensions, perhaps the most dangerous of all being the reawakened remnants of a warlike race called "Man."
In the Golden Age of Isaac Asimov and Robert A. Heinlein, Clifford D. Simak's writing blazed as brightly as anyone's in the science fiction firmament. Winner of the International Fantasy Award, City is a magnificent literary metropolis filled with an astonishing array of interlinked stories and structures—at once dystopian, transcendent, compassionate, and visionary.
The third author to be honored as a Grand Master of Science Fiction by the Science Fiction and Fantasy Writers Association (SFWA), Clifford D. Simak also received three Hugo Awards, a Nebula Award, an International Fantasy Award, and a Bram Stoker Lifetime Achievement Award.
