Kidnapped humans.
Network Effect
Mystery · Sci-Fi · Hard Sci-Fi

Kidnapped humans. Unwanted reunions. Zero downtime for binging media.

About the book
Murderbot just wants to binge its favorite shows in peace. Instead, it’s dealing with kidnapped humans, a sudden rescue mission, and an old frenemy in urgent need of help.
In Network Effect, the first full-length novel in Martha Wells’ Hugo, Nebula, and Locus Award–winning Murderbot Diaries, everyone’s favorite anxiety-ridden, media-obsessed security unit is once again pulled into a life-or-death situation it absolutely didn’t ask for. Armed with sarcasm, weaponized competence, and zero patience, Murderbot must decide if saving the humans (again) is really worth it.
Full of razor-sharp wit, action, and deeply relatable A.I. angst, Network Effect delivers everything fans love—now with more pages, more problems, and more Murderbot.

About the book
Benny is so nice they feel compelled to destroy him, but he has a friend who should scare the hell out of them in this breathtaking new kind of thriller by #1 New York Times bestselling master of suspense Dean Koontz.
Benny Catspaw’s perpetually sunny disposition is tested when he loses his job, his reputation, his fiancée, and his favorite chair. He’s not paranoid. Someone is out to get him. He just doesn’t know who or why. Then Benny receives an inheritance from an uncle he’s never heard of: a giant crate and a video message. All will be well in time.
How strange—though it’s a blessing, his uncle promises. Stranger yet is what’s inside the crate. He’s a seven-foot-tall self-described “bad weather friend” named Spike whose mission is to help people who are just too good for this world. Spike will take care of it. He’ll find Benny’s enemies. He’ll deal with them. This might be satisfying if Spike wasn’t such a menacing presence with terrifying techniques of intimidation.
In the company of Spike and a fascinated young waitress-cum-PI-in-training named Harper, Benny plunges into a perilous high-speed adventure, the likes of which never would have crossed the mind of a decent guy like him.

AN ELLE BEST BOOK OF THE YEAR
For twenty years, Sciona has devoted every waking moment to the study of magic, fueled by a mad desire to achieve the impossible: to be the first woman ever admitted to the High Magistry at the University of Magics and Industry.
When Sciona finally passes the qualifying exam and becomes a highmage, she finds her challenges have just begun. Her new colleagues are determined to make her feel unwelcome—and, instead of a qualified lab assistant, they give her a janitor.
What neither Sciona nor her peers realize is that her taciturn assistant was not always a janitor. Ten years ago, he was a nomadic hunter who lost his family on their perilous journey from the wild plains to the city. But now he sees the opportunity to understand the forces that decimated his tribe, drove him from his homeland, and keep the privileged in power.
At first, mage and outsider have a fractious relationship. But working together, they uncover an ancient secret that could change the course of magic forever—if it doesn’t get them killed first.

About the book
The New York Times Bestselling series is now available in Kindle Unlimited for the first time and includes an exclusive NEW novella at the end.
They dive so humanity survives…
More than two centuries after World War III poisoned the planet, the final bastion of humanity lives on massive airships circling the globe in search of a habitable area to call home. Aging and outdated, most of the ships plummeted back to earth long ago. The only thing keeping the two surviving lifeboats in the sky are Hell Divers—men and women who risk their lives by skydiving to the surface to scavenge for parts the ships desperately need.
When one of the remaining airships is damaged in an electrical storm, a Hell Diver team is deployed to a hostile zone called Hades. But there’s something down there far worse than the mutated creatures discovered on dives in the past—something that threatens the fragile future of humanity.

About the book
A spellbinding novel set in the universe of Isaac Asimov’s classic Galactic Empire series and Foundation series
Due to circumstances within our control . . . tomorrow will be canceled.
The Eternals, the ruling class of the Future, had the power of life and death not only over every human being but over the very centuries into which they were born. Past, Present, and Future could be created or destroyed at will.
You had to be special to become an Eternal. Andrew Harlan was special. Until he committed the one unforgivable sin—falling in love.
Eternals weren’t supposed to have feelings. But Andrew could not deny the sensations that were struggling within him. He knew he could not keep this secret forever. And so he began to plan his escape, a plan that changed his own past . . . and threatened Eternity itself.

Killed by a freak accident and reborn a century later, Marine Henry Morgan awakens as the governing AI of humanity’s first military starship.
I, Starship
Sci-Fi · First Contact · Space Opera
Our take
Killed by a freak accident and reborn a century later, Marine Henry Morgan awakens as the governing AI of humanity’s first military starship. With no rights and total responsibility, he’s sent to face a growing alien threat. Sharp, fast paced science fiction blends military action with dark humor as a very human mind pilots a very inhuman warship.
Choose your retailer
About the book
As a Marine, Henry Morgan would have said it was more likely he’d die from enemy fire than from being struck by a flying lawnmower while at a baseball game.
But it was the lawnmower that ended up taking him out.
A century later, Henry wakes up as a reconstituted intelligence, and is promptly drafted to be the governing AI for America’s first military starship. After decades of model-trained AIs wreaking havoc across the globe, humanity is ready to try something a little more…human.
Henry is perfect. For one thing, as a reconstituted intelligence, he has no rights and can be forced to do the bidding of the powers that be. For another, he’s the only Heritage Mind™ with any military experience that survived the Great Power Surge of 2072.
So, Henry’s it.
Blastoff, good Henry! Our hopes and dreams go with you. Oh, and while you’re at it, could you take a look at the aliens setting up shop in our asteroid belt? They seem to be…multiplying.
