About the book
Chris Barton leads a quiet life as a government mathematician—until everything unravels. One day, his car vanishes. When he gets home, a stranger is living in his house… claiming to be him.
Suddenly, Chris is erased.
His identity stolen, his life rewritten, he finds himself hunted by ruthless assassins and thrust into a surreal maze of clues that may—or may not—be real. Every step forward pulls him deeper into a conspiracy so twisted, it defies logic.
Now Chris must solve the riddle that stole his life, before the next bullet finds him. And with every answer comes a new question: who’s really pulling the strings—and why?
From the legendary author of I Am Legend, this is paranoia turned masterwork.

About the book
They escaped the deep. But the horror followed them to the surface.

Now the creatures have surfaced. They're faster. Smarter. And hungrier.
A Japanese trawler is a floating graveyard. A luxury yacht is torn apart. A Coast Guard crew is slaughtered. The infection is spreading—and it all began with one man’s dream of reaching Mars.
Dark Tide Rising is a relentless sci-fi horror sequel from deep-sea expert David M. Salkin. If you thought the nightmare ended in Deep Black Sea… it’s only just begun.

About the book
A masterpiece ahead of its time, a prescient rendering of a dark future, and the inspiration for the blockbuster film Blade Runner
By 2021, the World War has killed millions, driving entire species into extinction and sending mankind off-planet. Those who remain covet any living creature, and for people who can’t afford one, companies built incredibly realistic simulacra: horses, birds, cats, sheep. They’ve even built humans. Immigrants to Mars receive androids so sophisticated they are indistinguishable from true men or women. Fearful of the havoc these artificial humans can wreak, the government bans them from Earth. Driven into hiding, unauthorized androids live among human beings, undetected. Rick Deckard, an officially sanctioned bounty hunter, is commissioned to find rogue androids and “retire” them. But when cornered, androids fight back—with lethal force.

About the book
Sergeant Gastovsky—Gas to everyone except his superiors—never planned on joining the military. But when a con gone sideways lands him in power armor, he figures he might as well make it work… and maybe work a few side hustles while he’s at it.
Three years into a six-year contract, Gas is the go-to guy for getting things under the table. But when a squadmate is left behind in the chaos of a senseless battle, Gas sees his shot at a real legacy—and a real payday.
Assembling a team of misfit soldiers for a daring, off-the-books rescue-slash-heist, Gas takes aim at corrupt commanders, enemy lines, and the big score that could change everything.
It’s Ocean’s Eleven in space—with bullets, betrayal, and the best kind of bad decisions.

About the book
The firewall is down. The real war begins.
After escaping the deadly wasteland, Taimin and Selena thought freedom meant safety. Instead, it brings them face to face with the bonded—an ancient, ruthless enemy determined to wipe them out.
As the white city of Zorn faces annihilation, Selena calls upon every ounce of her mystic power to defend it. Meanwhile, Taimin journeys to Agravida, heart of the bonded empire, desperate to uncover their weakness before it’s too late.
Their only hope may lie in reaching out to the stars—calling upon long-forgotten ancestors with the power to shift the tide of battle. But time is running out, and the bonded aren’t the only threat waiting in the dark.
Survival isn’t freedom. It’s just the beginning of the fight.

In Kindred, Octavia E. Butler’s time-travel masterpiece, a Black woman is pulled from 1976 to a slave plantation in 1800s Maryland—forced to ensure the birth of her family line by protecting the white man who assaults her ancestor.

About the book
Experience the time travel science fiction classic from the New York Times bestselling author of Parable of the Sower and winner of the MacArthur “Genius” Grant, Nebula, and Hugo Awards.
A modern Black woman is pulled through time to face the horrors of slavery in this “Great American Novel” about racism, sexism, and white supremacy—then and now (The Atlantic).
“I lost an arm on my last trip home. My left arm.”
Dana’s torment begins when she suddenly vanishes on her 26th birthday from California, 1976, and is dragged through time to antebellum Maryland to rescue a boy named Rufus, heir to a slaveowner’s plantation. She soon realizes the purpose of her summons to the past: protect Rufus to ensure his assault of her Black ancestor so that she may one day be born. As she endures the traumas of slavery and the soul-crushing normalization of savagery, Dana fights to keep her autonomy and return to the present.
Blazing the trail for neo-slavery narratives like Colson Whitehead’s The Underground Railroad and Ta-Nehisi Coates’s The Water Dancer, Butler takes one of speculative fiction’s oldest tropes and infuses it with lasting depth and power. Dana not only experiences the cruelties of slavery on her skin but also grimly learns to accept it as a condition of her own existence in the present. “Where stories about American slavery are often gratuitous, reducing its horror to explicit violence and brutality, Kindred is controlled and precise” (New York Times).
“Reading Octavia Butler taught me to dream big, and I think it’s absolutely necessary that everybody have that freedom and that willingness to dream.”

Our take
The Born of Ash sequel is here—full of starships, lost empires, and a girl with the power to rewrite the galaxy. With 4.8 stars on Amazon, this sci-fi epic throws Keira into the wreckage of the First Galactic Empire to uncover the truth about her past, her power, and the Infinity Controller everyone wants to claim.

About the book
The war is over. The empire is ashes. Or so everyone thought.
Keira barely survived the regulators of the Unified Planetary Government. Now she's stranded aboard the Seringapatam, a ghost ship from the dying days of the First Galactic Empire—one still loyal to a mission that began before her birth.
With allies dead or dying and a strange new power awakening inside her, Keira learns the ship’s true objective: recover the mythical Infinity Controller, hidden deep within a planet’s core.
She’s been named heir to an empire that may no longer exist, caught between the agendas of a wary crew, the remnants of a fallen dynasty, and the return of a relentless enemy.
The stakes? Control of the galaxy.
And she doesn’t even trust herself.
