About the book
THE BASIS FOR SILO, NOW A #1 STREAMING SHOW ON APPLE TV
“One of dystopian fiction’s masterpieces alongside the likes of 1984 and Brave New World." — Daily Express
The first book in the acclaimed, New York Times best-selling trilogy, Wool is the story of mankind clawing for survival. The world outside has grown toxic, the view of it limited, talk of it forbidden. The remnants of humanity live underground in a single silo.
But there are always those who hope, who dream. These are the dangerous people, the residents who infect others with their optimism. Their punishment is simple. They are given the very thing they want: They are allowed to go outside.
After the previous sheriff leaves the silo in a terrifying ritual, Juliette, a mechanic from the down deep, is suddenly and inexplicably promoted to the head of law enforcement. With newfound power and with little regard for the customs she is supposed to abide, Juliette uncovers hints of a sinister conspiracy. Tugging this thread may uncover the truth . . . or it could kill every last human alive.

Power built on artificial lives begins to fracture under the weight of ambition.
Tower of Glass
Sci-Fi · Hard Sci-Fi
Our take
Power built on artificial lives begins to fracture under the weight of ambition. Industrialist Simeon Krug has reshaped society with android labor and now seeks to reach distant aliens by constructing a mile-high tower in the Arctic. As his creations demand equality and his heir resists succession, Tower of Glass explores authority, identity, and rebellion through character-driven science fiction.
Choose your retailer
About the book
From the Hugo and Nebula Award–winning author: "High adventure, considerable tension, and—most important—social consciousness" (Harlan Ellison).
Simeon Krug is the king of the universe. A self-made man, he is the Bill Gates of the era, having built a megacommercial empire on the backs of his products: androids, genetically engineered human slaves. Having amassed incredible wealth, his next major goal is to communicate with aliens living in an uninhabitable world, sending a mysterious signal. This requires building a mile high tower in the arctic tundra.
The androids want civil equality with humans, but are divided on the best means to the goal—political agitation or religious devotion to Krug, their creator. And Krug's son, Manuel, is reluctant to step into his role as heir to his father's empire.

About the book
A political conspiracy ensnares a student visiting Earth from an orbiting colony in this classic sci-fi trilogy opener by the author of The Forever War.
By the close of the twenty-first century, almost half a million souls have already abandoned Earth to live in satellites orbiting the strife-ridden planet. Each of these forty-one Worlds is an independent entity boasting its own government and culture, yet each remains bound to the troubled home World by economic pressure.
A brilliant student of political science born and raised in New New York, the largest of the orbiting Worlds, young Marianne O'Hara has never been to the surface but now has a golden opportunity to continue her studies far below her floating home of steel. Life on Earth, however, is very different from anything she has ever experienced.
With power in the hands of a privileged few and unrest running rampant, the allure of radical politics might be too much for an idealistic and inexperienced young World dweller to resist. But even the best of intentions can have disastrous consequences, and Marianne soon finds herself unwittingly drawn into a wide-ranging conspiracy that could result in the total destruction of everything on Earth . . . and above.
The first book in the acclaimed science fiction trilogy by Hugo and Nebula Award–winning author Joe Haldeman, Worlds offers a powerful vision of a possible future.

A group of strangers bound by terrifying synchronicity becomes humankind’s hope of survival in an exhilarating, twist-filled novel by Dean Koontz, the #1 New York Times bestselling master of suspense.
As a girl, Joanna Chase thrived on Rustling Willows Ranch in Montana until tragedy upended her life.

Choose your retailer
About the book
Anders Jensen just wants a quiet life, a steady job, and maybe a girlfriend who doesn’t throw punches in dive bars. Instead, he’s broke, genetically enhanced, and roommates with a sketchy data thief in a half-collapsed apartment near a crack house.
Then a plague hits Hagerstown, and things go from weird to “dodging government assassins” real fast.
In a world where the genetically engineered rule and the rest barely scrape by, Anders is stuck somewhere in the middle—an anomaly with a PhD and a death wish. But with a cyborg best friend, a chaotic girlfriend, and a hipster magician who may or may not be humanity’s last hope, Anders is suddenly the least dangerous person in the room.
The end of the world is here. And it’s weirdly personal.

After global warming and a second civil war devastated the former United States, two different societies rose from the ashes – the Union, a towering high-tech utopia, hugging the perimeter of the continent, and the devastated, untamed midsection known as the Ruins.

Dystopian · Sci-Fi
Our take
John Hopper has spent decades in solitude, but when a scientist warns of an impending extinction-level comet, he prepares to face the apocalypse alone. Then Yely, the troubled teen next door, changes everything. As disaster looms, Ripley—once thought the safest place on Earth—may become the worst. A gripping tale of survival, redemption, and unexpected connections.
Choose your retailer
About the book
Forty years later, the pain of his personal tragedy still echoes within John Hopper. He retreats to the small town, Ripley, West Virginia, and is content being alone and in peace. He spends his evenings as an amateur podcast host, anonymously broadcasting rants about what is wrong with the world. Through a faithful listener and scientist, Jarvis, John finds out about the impending comet impact, possibly, an extinction level event.
With no beneficiary and ample time to prepare, John uses all his money to get everything he needs to survive the end of the world … alone. What John doesn’t realize is that meeting Yely, the problematic teenage girl who moved in next door, changes things.
All may not be as expected. John not only finds himself bringing people into his shelter, he learns that Ripley, the predicted safest place on earth, may very well become one of the worst places imaginable
