The Stand by Stephen King

A patient escapes from a biological testing facility, unknowingly carrying a deadly weapon: a mutated strain of super-flu that will wipe out 99 percent of the world’s population within a few weeks. Those who remain are scared, bewildered, and in need of a leader. Two emerge—Mother Abagail, the benevolent 108-year-old woman who urges them to build a peaceful community in Boulder, Colorado; and Randall Flagg, the nefarious “Dark Man,” who delights in chaos and violence. As the dark man and the peaceful woman gather power, the survivors will have to choose between them—and ultimately decide the fate of all humanity.

Into the Drowning Deep by Mira Grant 

The ocean is home to many myths,

But some are deadly. . .

Seven years ago the Atargatis set off on a voyage to the Mariana Trench to film a mockumentary bringing to life ancient sea creatures of legend. It was lost at sea with all hands. Some have called it a hoax; others have called it a tragedy.

Now a new crew has been assembled. But this time they're not out to entertain. Some seek to validate their life's work. Some seek the greatest hunt of all. Some seek the truth. But for the ambitious young scientist Victoria Stewart this is a voyage to uncover the fate of the sister she lost.

Whatever the truth may be, it will only be found below the waves.

But the secrets of the deep come with a price.

Annihilation by Jeff VanderMeer

Area X has been cut off from the rest of the continent for decades. Nature has reclaimed the last vestiges of human civilization. The first expedition returned with reports of a pristine, Edenic landscape; the second expedition ended in mass suicide; the third expedition in a hail of gunfire as its members turned on one another. The members of the eleventh expedition returned as shadows of their former selves, and within weeks, all had died of cancer. In Annihilation, the first volume of Jeff VanderMeer's Southern Reach trilogy, we join the twelfth expedition.

Cursed Bunny by Bora Chung Translated by Anton Hur 

From an author never before published in the United States, Cursed Bunny is unique and imaginative, blending horror, sci-fi, fairy tales, and speculative fiction into stories that defy categorization. By turns thought-provoking and stomach-turning, here monsters take the shapes of furry woodland creatures and danger lurks in unexpected corners of everyday apartment buildings. But in this unforgettable collection, translated by the acclaimed Anton Hur, Chung’s absurd, haunting universe could be our own.
 
“The Head” follows a woman haunted by her own bodily waste. “The Embodiment” takes us into a dystopian gynecology office where a pregnant woman is told that she must find a father for her baby or face horrific consequences. Another story follows a young monster, forced into underground fight rings without knowing his own power. The titular fable centers on a cursed lamp in the shape of a rabbit, fit for a child’s bedroom but for its sinister capabilities.
 
No two stories are alike, and readers will be torn whether to race through them or savor Chung’s wit and frenetic energy on every page. Cursed Bunny is a book that screams to be read late into the night and passed on to the nearest set of hands the very next day. 

“Like the work of Carmen Maria Machado and Aoko Matsuda, Chung’s stories are so wonderfully, blisteringly strange and powerful that it's almost impossible to put Cursed Bunny down.” ―Kelly Link, bestselling author of Get In Trouble

Blood Music by Greg Bear

This Hugo and Nebula Award finalist follows present-day events in which the fears concerning the nuclear annihilation of the world subsided after the Cold War and the fear of chemical warfare spilled over into the empty void it left behind. An amazing breakthrough in genetic engineering made by Vergil Ulam is considered too dangerous for further research, but rather than destroy his work, he injects himself with his creation and walks out of his lab, unaware of just how his actions will change the world. Author Greg Bear’s treatment of the traditional tale of scientific hubris is both suspenseful and a compelling portrait of a new intelligence emerging amongst us, irrevocably changing our world.

Blindsight by Peter Watts 

Two months since the stars fell...

Two months of silence, while a world held its breath.

Now some half-derelict space probe, sparking fitfully past Neptune's orbit, hears a whisper from the edge of the solar system: a faint signal sweeping the cosmos like a lighthouse beam. Whatever's out there isn't talking to us. It's talking to some distant star, perhaps. Or perhaps to something closer, something en route.

So who do you send to force introductions with unknown and unknowable alien intellect that doesn't wish to be met?

You send a linguist with multiple personalities, her brain surgically partitioned into separate, sentient processing cores. You send a biologist so radically interfaced with machinery that he sees x-rays and tastes ultrasound. You send a pacifist warrior in the faint hope she won't be needed. You send a monster to command them all, an extinct hominid predator once called vampire, recalled from the grave with the voodoo of recombinant genetics and the blood of sociopaths. And you send a synthesist—an informational topologist with half his mind gone—as an interface between here and there.

Pray they can be trusted with the fate of a world. They may be more alien than the thing they've been sent to find.

Frankenstein by Mary Shelley

Nominated as one of America’s best-loved novels by PBS’s The Great American Read
 
The original 1818 text of Frankenstein preserves the hard-hitting and politically-charged aspects of Shelley’s original writing, as well as her unflinching wit and strong female voice. This edition also emphasizes Shelley’s relationship with her mother—trailblazing feminist Mary Wollstonecraft, who penned A Vindication of the Rights of Woman—and demonstrates her commitment to carrying forward her mother’s ideals, placing her in the context of a feminist legacy rather than the sole female in the company of male poets, including Percy Shelley and Lord Byron.
 
This edition includes a new introduction and suggestions for further reading by National Book Critics Circle award-winner and Shelley expert Charlotte Gordon, literary excerpts and reviews selected by Gordon, and a chronology and essay by preeminent Shelley scholar Charles E. Robinson.

Carrion Comfort by Dan Simmons 

Embraced by giants such as Stephen King and Dean R. Koontz, Dan Simmons's Carrion Comfort was originally published by Warner Books in 1989, and remains a classic of dark fantasy and horror.

"One of the three greatest horror novels of the 20th century. Simple as that." --Stephen King

THE PAST... Caught behind the lines of Hitler's Final Solution, Saul Laski is one of the multitudes destined to die in the notorious Chelmno extermination camp. Until he rises to meet his fate and finds himself face to face with an evil far older, and far greater, than the Nazi's themselves…

THE PRESENT... Compelled by the encounter to survive at all costs, so begins a journey that for Saul will span decades and cross continents, plunging into the darkest corners of 20th century history to reveal a secret society of beings who may often exist behind the world's most horrible and violent events. Killing from a distance, and by darkly manipulative proxy, they are people with the psychic ability to 'use' humans: read their minds, subjugate them to their wills, experience through their senses, feed off their emotions, force them to acts of unspeakable aggression. Each year, three of the most powerful of this hidden order meet to discuss their ongoing campaign of induced bloodshed and deliberate destruction.

But this reunion, something will go terribly wrong. Saul's quest is about to reach its elusive object, drawing hunter and hunted alike into a struggle that will plumb the depths of mankind's attraction to violence, and determine the future of the world itself…

Sphere by Michael Crichton

From the author of Jurassic Park, Timeline, and Congo comes a psychological thriller about a group of scientists who investigate a spaceship discovered on the ocean floor.

In the middle of the South Pacific, a thousand feet below the surface, a huge vessel is unearthed. Rushed to the scene is a team of American scientists who descend together into the depths to investigate the astonishing discovery. What they find defies their imaginations and mocks their attempts at logical explanation. It is a spaceship, but apparently it is undamaged by its fall from the sky. And, most startling, it appears to be at least three hundred years old, containing a terrifying and destructive force that must be controlled at all costs.
