The Kaiju Preservation Society
Sci-Fi · Alien Invasion · First Contact
Our take
When the pandemic leaves Jamie Gray stuck in gig work, a chance encounter leads to a job with a mysterious team caring for creatures in an alternate dimension—giant kaiju roaming a world free of humans. But others have crossed over with reckless intentions, threatening both realities. John Scalzi delivers a sharp, high-energy standalone adventure filled with peril and wonder.
Choose your retailer
About the book
The Kaiju Preservation Society is John Scalzi's first standalone adventure since the conclusion of his New York Times bestselling Interdependency trilogy.
When COVID-19 sweeps through New York City, Jamie Gray is stuck as a dead-end driver for food delivery apps. That is, until Jamie makes a delivery to an old acquaintance, Tom, who works at what he calls “an animal rights organization.” Tom’s team needs a last-minute grunt to handle things on their next field visit. Jamie, eager to do anything, immediately signs on.
What Tom doesn't tell Jamie is that the animals his team cares for are not here on Earth. Not our Earth, at least. In an alternate dimension, massive dinosaur-like creatures named Kaiju roam a warm, human-free world. They're the universe's largest and most dangerous panda and they're in trouble.
It's not just the Kaiju Preservation Society who have found their way to the alternate world. Others have, too. And their carelessness could cause millions back on our Earth to die.

Our take
In The Darkening, strange summer snow and dimming daylight signal a global collapse as alien spores infect the world.

Choose your retailer
About the book
The sun is dimming, the world is ending, and the long journey south is only the beginning.
In the middle of summer, snow falls over Montana. Daylight dims to a ghostly twilight. And at night, glowing alien spores drift from the sky bringing a sickness that can twist the people you love into something unrecognizable. The air grows colder and the infected more dangerous with every passing day.
Nate Corwin, a science teacher, and his wife Paula, a nurse, know that their suburban home won’t hold for long. With their two children, Riley and Jonah, and their loyal golden retriever, Max, they set out for Paula’s family farm in Florida—one place they pray might still be safe—and warm.
But the road south is a gauntlet of horrors: parasite-driven killers, blizzards, collapsing refugee camps, and monsters that hunt in the dark. The only defense—UV light—is feeble at best, and the infected are starting to adapt.
As the alien bloom spreads and the world tilts toward madness, the Corwins will learn that survival isn’t just about keeping the monsters out, it’s about deciding how far you’re willing to go to protect the people you love.
The Darkening is a relentless, heart-pounding journey through a world where the sun is growing dark, the rules are gone, and every step could be your last.

About the book
Uncover a history of galactic evil.
"So this is how liberty dies—with thunderous applause." —Senator Padmé Amidala
When Sheev Palpatine declared the birth of his new Empire, he expected it would stand for thousands of years. Instead, it lasted
only 24. This is the story of how a tyrannical regime rose from the ashes of democracy, ruled the galaxy with an iron fist, and then collapsed into dust.
It is a story of war and heroes. It is a story of propaganda and the power of fascism. But most of all, it is a story of normal people trying to live their lives in the face of brutal dictatorship.
From the barbarity of Darth Vader's campaigns to the horrors of the Tarkin Initiative, this book offers new insights into the dark entity at the core of the Star Wars saga, with chapters covering economic strategy and political organisation, propaganda, crime and punishment, military tactics, and warfare, giving even the most expert Star Wars fans a fresh perspective on the Galactic Empire.

About the book
In this thrilling, action-packed fourth installment in the Planetside series from acclaimed science fiction author Michael Mammay, retired Colonel Carl Butler gears up for another military investigation, full of danger, corporate intrigue, and tech people would kill for—perfect for fans of John Scalzi and Craig Alanson.
Colonel Butler has paid his dues and just wants to enjoy his retirement on a remote planet. But the galaxy has had other plans. He has been roped into searching for a politician’s missing son and an industry magnate’s missing daughter. He has been kidnapped, violated numerous laws, and caused the destruction of colonial facilities. He’s famous—or infamous, depending on who you ask—praised and reviled in equal measure across the galaxy for his exploits.
And he is determined to never let the government drag him into another investigation.
But when a runaway twelve-year-old girl whose father has gone missing asks him for help, well…it’s a lot harder to say no.
The girl’s father, Jorge Ramiro, was supposed to have been on Taug, a moon orbiting the gas giant Ridia 5, working on a dig with a famous archaeologist. But now there’s no sign of him and no record of him being there. Mining operations on the moon are run by two different consortiums, Caliber and Omicron—both of which have tried to kill Butler in the past. Butler doesn’t believe in coincidence.
Landing on Taug with his right-hand man Mac, computer genius Ganos, and an elite security squad, Butler soon finds that they’ve charged back into the crosshairs—because Ramiro is not the only who has disappeared, and the perpetual darkside of this moon is hiding more than the truth about a missing archeologist…

Our take
Desperate for rest after a year of grief and nightmares, Iris arrives early at a secluded Catskills lake house and sees a blood soaked stranger burying something behind the deck.

About the book
NO ONE’S AROUND FOR MILES…
One year ago, Iris’s world turned upside down. Haunted by nightmares of her mother’s traumatic death, Iris has become a sleep-deprived, jittery version of herself who she hardly recognizes anymore. So when she’s given the opportunity to get away from the crushing grind of reality for a relaxing week with her partner and his close-knit group of friends, she jumps at the chance.
But after she arrives early to the remote lake house in the Catskills, things take a dark turn. Alone in the cabin in the middle of the night, Iris sees a blood-covered man burying something—or someone—in the mud behind the deck before entering the house. But the daylight reveals nothing, the dirt unturned and the house pristine.
As strange and increasingly disturbing discoveries begin to stack up, her fellow house guests refuse to take anything Iris has to say seriously, and she begins to suspect that someone might be gaslighting her. If the stress hasn’t finally gotten to her, that is. Determined to uncover the truth, Iris finds herself drawn into a terrifying game of cat and mouse. Is it all in her head, or is there really a killer among them? Can she trust anyone…even herself?

About the book
New York Times Bestseller
A New York Times Notable Book
The #1 New York Times bestselling author of Seveneves, Anathem, Reamde, and Cryptonomicon returns with a wildly inventive and entertaining science fiction thriller—Paradise Lost by way of Philip K. Dick—that unfolds in the near future, in parallel worlds.
In his youth, Richard “Dodge” Forthrast founded Corporation 9592, a gaming company that made him a multibillionaire. Now in his middle years, Dodge appreciates his comfortable, unencumbered life, managing his myriad business interests, and spending time with his beloved niece Zula and her young daughter, Sophia.
One beautiful autumn day, while he undergoes a routine medical procedure, something goes irrevocably wrong. Dodge is pronounced brain dead and put on life support, leaving his stunned family and close friends with difficult decisions. Long ago, when a much younger Dodge drew up his will, he directed that his body be given to a cryonics company now owned by enigmatic tech entrepreneur Elmo Shepherd. Legally bound to follow the directive despite their misgivings, Dodge’s family has his brain scanned and its data structures uploaded and stored in the cloud, until it can eventually be revived.
In the coming years, technology allows Dodge’s brain to be turned back on. It is an achievement that is nothing less than the disruption of death itself. An eternal afterlife—the Bitworld—is created, in which humans continue to exist as digital souls.
But this brave new immortal world is not the Utopia it might first seem . . .
Fall, or Dodge in Hell is pure, unadulterated fun: a grand drama of analog and digital, man and machine, angels and demons, gods and followers, the finite and the eternal. In this exhilarating epic, Neal Stephenson raises profound existential questions and touches on the revolutionary breakthroughs that are transforming our future. Combining the technological, philosophical, and spiritual in one grand myth, he delivers a mind-blowing speculative literary saga for the modern age.

Cascade Failure
Sci-Fi · Genetic Engineering · Space Opera
Our take
Guild deserter Jal falls in with the oddball crew of the Ambit, a ship run by an AI and staffed by misfits who answer a distress call on a dead world. A lone survivor reveals a corporate plot that has already claimed multiple planets. Cascade Failure delivers fast paced sci fi with found family, danger, and heart.
Choose your retailer
About the book
L. M. Sagas's debut, Cascade Failure, is a high-octane, sci-fi adventure blending J. S. Dewes's Divide series with Firefly. It features a fierce, messy, chaotic space family, vibrant worlds, and an exploration of the many ways to be—and not to be—human.

There are only three real powers in the Spiral: the corporate power of the Trust versus the Union's labor's leverage. Between them the Guild tries to keep everyone's hands above the table. It ain't easy.
Branded a Guild deserter, Jal "accidentally" lands a ride on a Guild ship. Helmed by an AI, with a ship's engineer/medic who doesn't see much of a difference between the two jobs, and a "don't make me shoot you" XO, the Guild crew of the Ambit is a little . . . different.
They're also in over their heads. Responding to a distress call from an abandoned planet, they find a mass grave, and a live programmer who knows how it happened. The Trust has plans. This isn't the first dead planet, and it's not going to be the last.
Unless the crew of the Ambit can stop it.

On Borthan, revealing one’s inner self is a crime punishable by exile or death.
A Time of Changes
Dystopian · Sci-Fi
Our take
On Borthan, revealing one’s inner self is a crime punishable by exile or death. When a visitor from Earth opens Kinnall Darival’s eyes to a different way of living, he risks everything to challenge the Covenant that governs his world. With 4.0 stars on Amazon and over three thousand Goodreads ratings, A Time of Changes offers a powerful classic of rebellion and identity.
Choose your retailer
About the book
On the distant world of Borthan, the Covenant shapes every aspect of life, forbidding its people from sharing their innermost thoughts. To speak of oneself is considered obscene, and those who break this law face exile or death. Born into privilege as the prince of Salla, Kinnall Darival has always accepted these rules as unchangeable truths.
Everything shifts when a traveler from Earth reveals a different way of living, one in which openness is not a crime but a path to connection. Drawn to forbidden knowledge, Kinnall begins to question the foundations of his society and the cost of a life lived in silence. His choice to challenge the Covenant ignites a rebellion that could transform Borthan forever.
With 4.0 stars on Amazon and more than three thousand Goodreads ratings, A Time of Changes stands as a celebrated Nebula Award winning classic.

The unicorn girl is on a desperate hunt in the series by the New York Times–bestselling, Nebula-winning authors: "Fast-paced action . . . entertaining fare indeed." —Booklist

Wanderers
Post-Apocalyptic · Dystopian · Horror · Sci-Fi
Our take
A mysterious sleepwalking epidemic turns a family crisis into a national fracture, drawing strangers across America while fear spreads faster than the illness itself. Wanderers follows Shana, the shepherds, and the flock they protect as society unravels around them, blending pandemic suspense, apocalyptic dread, and survival fiction into a sprawling story of collapse and connection.

About the book
A decadent rock star. A deeply religious radio host. A disgraced scientist. And a teenage girl who may be the world’s last hope. From the mind of Chuck Wendig comes “a magnum opus . . . a story about survival that’s not just about you and me, but all of us, together” (Kirkus Reviews, starred review).
NOMINATED FOR THE BRAM STOKER AWARD • ONE OF THE BEST BOOKS OF THE YEAR: The Washington Post, NPR, The Guardian, Kirkus Reviews, Publishers Weekly, Library Journal, Polygon
Shana wakes up one morning to discover her little sister in the grip of a strange malady. She appears to be sleepwalking. She cannot talk and cannot be woken up. And she is heading with inexorable determination to a destination that only she knows. But Shana and her sister are not alone. Soon they are joined by a flock of sleepwalkers from across America, on the same mysterious journey. And like Shana, there are other “shepherds” who follow the flock to protect their friends and family on the long dark road ahead.
For as the sleepwalking phenomenon awakens terror and violence in America, the real danger may not be the epidemic but the fear of it. With society collapsing all around them—and an ultraviolent militia threatening to exterminate them—the fate of the sleepwalkers depends on unraveling the mystery behind the epidemic. The terrifying secret will either tear the nation apart—or bring the survivors together to remake a shattered world.
