About the book
She hides from the world. He’s the monster who refuses to let her vanish.
Rose has spent her life running. From hunger, from pain, from anyone who dared to care for her. Once a street thief, then a reluctant priestess, then a prize in a gladiator’s arena, she’s learned that safety only comes from silence. From disappearing into dreams and a false reality that has always kept her safe.
Until Gunnar finds her.
The troll warrior with eyes like storm clouds and hands that could shatter stone. The moment he sees her, he knows she’s his, and that claiming her will take more than brute strength. It will take patience. Trust. The slow, dangerous surrender of her heart.
But the realm is changing. Humans are flooding into the troll kingdom, and the king has declared bridal games—a brutal contest to bind humans and trolls in marriage. Rose is fragile, untrained, and has no wish to compete. Gunnar can’t bear to see her offered to another.
So he enters the games himself. To fight for her. To prove his worth. Even if it means pretending he could ever want anyone but her.
Because monsters may not dream, but for Rose, Gunnar will tear apart the waking world itself.

About the book
A jaded homicide detective working a serial murder case is teamed up with a new partner—a law enforcer from an alien race
Big-city life in the near future is full of violence and tension for Saigo City homicide detective David Silver. His latest assignment is to track down a serial killer dubbed "Machete Man" because he hacks his victims to pieces. But Silver and his partner Mel Burnett just caught a break: One of Machete Man's intended victims—an elderly woman who would've been number six—escapes. And the killer left some DNA behind. Too bad the bureaucrats in charge have brought in a third wheel to assist the Homicide Task Force. Hailing from a superior race gifted with advanced technology, the Elaki have come to Earth to advise in everything from politics to medicine to big business—and now, it seems, police fieldwork. Standing seven feet tall with scales that ripple in the breeze, String resembles a stingray and smells like fresh lime. But he's turning out to be an unexpected asset in a case that's quickly morphing into something even more sinister: a far-reaching conspiracy that could leave a lot more people dead, including Detective Silver.
A twisting, complex crime tale with intriguing characters, including Silver's DEA- turned-enforcer wife, Rose, and an Elaki named the Puzzle Solver, Alien Blues realistically depicts a world in which aliens and humans can coexist.

Our take
At ninety-four, Mia Ziemann has already lived through a future where technology has made long life possible, comfortable, and deeply boring. After a radical treatment restores her body and mind to youth, Holy Fire sends her into a strange post-human world of art, desire, designer drugs, and reinvention. Rated 4.1 on Amazon and 3.7 on Goodreads, with praise from Wired and Publishers Weekly.

About the book
Memory, morality, and immortality merge in this "haunting and lyrical triumph" from the bestselling author of Schismatrix Plus (Time).
In the late twenty-first century, technology has lengthened lifespans far beyond what was once medically possible. Existence itself has become relatively easy—if boring. In this futuristic paradise, ninety-four-year-old Mia Ziemann longs for something different and undergoes a radical new treatment that restores both her body and mind to that of a twenty-year-old. After her dramatic transformation, Mia finds herself lost in an avant-garde world of passion, designer drugs, and creative expression . . .
"Ideas—big ideas—lurk beneath Mia's romp through Sterling's delightfully imagined newly post-human Earth. Art, artifice, the pursuit of immortality, and youth and aging bounce around the story, the characters, and their conversations in imaginative, engaging fashion. . . . In the end, Holy Fire is one of the most interesting, imaginative, and subtly humorous—and relevant for it—novels the cyberpunk/post-human era has produced. . . . Holy Fire may very well be [Sterling's] best work." —Speculiction
"An intellectual feat, it is also a treat for the spirit and the senses." —Wired
"A patented Sterling extra-special." —Newsday
"The future Sterling traces is plausible and provocative, particularly his consideration of several contrasting cultures, and of the disenfranchised who are unable to become 'post-human.' Those interested in serious speculative conversation set within a very strange near-future will find this much to their taste." —Publishers Weekly

About the book
The Nebula Award–winning author "continues to dazzle us with brilliance in combining science, romance and adventure." —Romantic Times
MIT professor Megan O'Flannery is one of the world's leading research scientists on artificial intelligence for androids. Most of her work consists of working with computer simulations, so when the company MindSim gives Megan an opportunity to work with an android, she jumps at the chance.
Hidden and secret, an underground compound in the Nevada desert offers Megan a spectacular lab where she can live and work, mostly alone except for robotic assistants—and the android. Although it appears physically indistinguishable from a human man, Megan realizes she has a lot of work ahead if he is ever to think and act like a human, let alone the superspy that MindSim wants him to be. She loosens the controls on his behavior, allowing the android—who soon chooses the name Ander—the freedom of more independent thought.
However, when Raj Sundaram, the reclusive genius of robotics, arrives at the compound to work with the android, Ander's behavior takes a strange turn, causing Megan to distrust Raj. As Ander's development spins out of control, he throws the project into chaos, going rogue even as he becomes stronger—and more dangerously human.
"This novel is clearly science fiction first with a dynamic climax that will stun the unsuspecting audience who will fail to break The Phoenix Code before Ms. Asaro reveals the ending of this keeper." —Painted Rock Reviews
"Cinematic energy and the ease and confidence of a seasoned bestseller." —SFReviews.net

Choose your retailer
About the book
A new standalone sci-fi novel from Edward Ashton, author of Mickey7 (the inspiration for the major motion picture Mickey 17).
Dalton Greaves is a hero. He’s one of humankind’s first representatives to Unity, a pan-species confederation working to bring all sentient life into a single benevolent brotherhood.
That’s what they told him, anyway. The only actual members of Unity that he’s ever met are Boreau, a giant snail who seems more interested in plunder than spreading love and harmony, and Boreau’s human sidekick, Neera, who Dalton strongly suspects roped him into this gig so that she wouldn’t become the next one of Boreau’s crew to get eaten by locals while prospecting.
Funny thing, though—turns out there actually is a benevolent confederation out there, working for the good of all life. They call themselves the Assembly, and they really don’t like Unity. More to the point, they really, really don’t like Unity’s new human minions.
When an encounter between Boreau’s scout ship and an Assembly cruiser over a newly discovered world ends badly for both parties, Dalton finds himself marooned, caught between a stickman, one of the Assembly’s nightmarish shock troops, the planet’s natives, who aren’t winning any congeniality prizes themselves, and Neera, who might actually be the most dangerous of the three. To survive, he’ll need to navigate palace intrigue, alien morality, and a proposal that he literally cannot refuse, all while making sure Neera doesn’t come to the conclusion that he’s worth more to her dead than alive.
Part first contact story, part dark comedy, and part bizarre love triangle, The Fourth Consort asks an important question: how far would you go to survive? And more importantly, how many drinks would you need to go there?
