About the book
Thomas never expected to find Excalibur stuck beneath a Welsh lake. He never asked to be a hero. And he certainly never imagined standing between a tyrant and the fate of a galaxy.
Destiny doesn’t wait for permission.
From the mystical world of Avalyeth, Thomas’ journey will lead him and his growing crew into the heart of enemy territory, the halls of ancient dragons, and the path of knights who remember a time when hope still burned bright. Hunted by the Draconite and haunted by the past, they’ll need to risk everything to outmaneuver and overcome those who would see them destroyed.
As new alliances form and old rivalries re-ignite, Thomas must prove he’s more than just the captain of a legendary starship—he must become the leader others believe him to be.
Even if he still isn’t sure he believes it himself.

About the book
In this epic sci-fi adventure for fans of The Expanse and Battlestar Galactica, five intrepid heroes must unite to save civilization after a long-dormant enemy awakens and strikes a devastating blow
“This jarring, engrossing story of a species-wide fight for survival is recommended for all science fiction readers.”—Publishers Weekly (starred review)
The galaxy was once terrorized by the Sturm, a group of “species purists” intent on destroying any human with genetic or cybernetic enhancements. Fashioning themselves as the one true “Human Republic,” the Sturm cut a bloody swath across the stars, killing billions before finally being defeated and driven into the far reaches of Dark Space. Centuries of peace bred complacency. Everyone believed the Sturm had died out in the Dark. They were wrong.
The enemy has returned and, with a brutal and decisive attack, knocks out almost all of humanity’s defenses. Now on the brink of annihilation, humankind’s only hope is a few brave souls who survived the initial attack: Commander Lucinda Hardy, thrust into uncertain command of the Royal Armadalen Navy’s only surviving warship. Booker3, a soldier of Earth, sentenced to die for treason, whose time on death row is cut short when the Sturm attack his prison compound. Princess Alessia, a young royal of the Montanblanc Corporation, forced to flee when her home planet is overrun and her entire family executed. Sephina L’trel, the leader of an outlaw band who must call on all of her criminal skills to resist the invasion. And, finally, Admiral Frazer McLennan, the infamous hero of the first war with the Sturm hundreds of years ago, who hopes to rout his old foes once and for all—or die trying.
These five flawed, reluctant heroes must band together to prevail against a relentless enemy and near-impossible odds. For if they fail, the future itself is doomed.

About the book
Triple Gold Winner — 2026 Spring BookFest Awards
First Place: Science Fiction Space Opera, YA Science Fiction, LGBTQ+ Science Fiction
New Edition — Book One in the Award-Winning YA Sci-Fi Series
Lily Starling is alone in a city she barely recognizes, with no memory of her past—only a metal tag bearing her name and an instinct for survival. When a Union starship crew claims she belongs with them, she's pulled centuries beyond her own time and into a desperate mission against the psionic Krythar.
Aboard the starship Salamander, Lily is drawn into a found family of misfit officers, warriors, and exiles. Together, they uncover mysteries hidden among the stars: an ancient memory seed carrying the voices of the dead—and a weapon capable of unraveling time itself.
But when Lily faces her greatest fear, she must choose—confront the truth of her past, or risk losing everything she's come to care about.
A lyrical, fast-paced space opera about identity, connection, and courage at the edge of the unknown.
Perfect for fans of Becky Chambers, with the cinematic scope of Mass Effect and the found-family heart of Firefly and Red Rising.

About the book
A genetically enhanced fighting force may be humanity's only hope in this novel by the #1 New York Times–bestselling author of Star Wars: Thrawn.
Decades after a successful invasion of Earth and the Terran Democratic Empire by the Ryqril—hostile, leathery-skinned aliens—resistance fighter Allen Caine is training for an undercover mission. He will assume the identity of an aide to the senate—part of the government that colludes with the invaders. But when the mission begins earlier than planned, Caine finds himself stuck on the off-planet outpost of Plinry with no idea of what awaits. He's responsible for the most important mission undertaken by the resistance in twenty years, and when the operation goes awry, Caine's only hope is to locate Plinry's so-called blackcollars—the elusive, martial arts–trained guerilla force whose wartime resistance efforts are legendary. With his life and the freedom of everyone in the TDE on the line, Caine's success will depend on whether or not he can find them. . . .

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

About the book
In a post-human future, sentient elephants who speak with the dead uncover a devastating secret in this "weird, wise, and worldly…triumph" (Hugo Award-winning author Robert J. Sawyer).
In a distant future, humans are extinct, but their successors—animals uplifted into walking, talking, sentient beings—thrive across the galaxy. The Fant are anthropomorphic elephants, exiled to the rainy ghetto world of Barsk. Though they are ostracized by other races, they develop essential medicines upon which all species depend. The most coveted is the drug Koph, which allows users to interact with the recently deceased and learn their secrets.
Now a shadowy group is forcing the Fant to surrender their knowledge and claim Koph for themselves. A Fant named Jorl is compelled to question his deceased best friend, who years ago mysteriously committed suicide. But in so doing, Jorl unearths a secret the powers that be would prefer to keep buried forever.
Meanwhile, his dead friend's son, a physically challenged young Fant named Pizlo, is driven by disturbing visions to take his first unsteady steps toward an uncertain future.

“One of the finest achievements of modern science fiction.”—The New York Times Book Review
The shadow of war has fallen on the Web. In the corridors of power on Tau Ceti Center, chaos reigns. Out of reach from the clashing empires, the artificial intelligences of the TechnoCore manipulate everyone and everything. And on Hyperion itself, where battle rages in the skies and on the streets, the mysterious Time Tombs are opening. And the secrets they contain mean that nothing—nothing anywhere in the universe—will ever be the same.

"A goodie. . . . Buy it, and join me in wondering what Mike will do with the next volumes in the series." —Analogon Eros Ascending
The Vainmill Syndicate owns a vast array of properties across the galaxy, and one of their biggest moneymakers is the Velvet Comet. A space station orbiting the planet Deluros VIII, the Comet is a luxurious pleasure palace, hosting the rich, the famous, and occasionally the infamous. It provides its customers with a private space in which to explore their deepest desires—and for one guest, a place to stir up trouble.

A soldier returns from captivity to a kingdom that would rather use him than welcome him home.
The Thirteenth Man
Sci-Fi · Galactic Empire · Military Sci-Fi · Space Opera
Our take
A soldier returns from captivity to a kingdom that would rather use him than welcome him home. When Commander Charlie Cass finds the Realm tangled in court intrigue and edging toward interstellar war, he must rely on tactical skill, stubborn resolve, and political instinct to survive. This military science fiction novel blends space opera, aristocratic conflict, and high-stakes strategy with a fast-moving sense of adventure.
Choose your retailer
About the book
From the author of The Treasons Cycle, The Gods Within, and The Dead Among Us series comes a stand-alone science fiction novel for fans of David Weber, Pierce Brown, Lois McMaster Bujold, and more! Spanning the galaxy, The Thirteenth Man blends the best traditions of space opera and military sci-fi into a non-stop adventure that's as much Patrick O'Brien as it is John Scalzi.
When Commander Charlie Cass, the bastard son of the Duke de Maris, returns from five years in a squalid Syndonese POW camp, he finds that little has changed in the Realm. As always, the King and the nine Dukes are conspiring against each other, but now some of them are plotting with Charlie's old enemy. And as interstellar war looms, they certainly don't need Charlie Cass messing up their delicate plans.
Unfortunately for them, that's what he's best at.
With ingenuity, tacticial inovations, and just a little bit of luck, Cass might be able to not only save the Realm, but perhaps even change it for the better.
Which, of course, means he'll likely face the headsman's axe.

Our take
A child with no voice and a past that defies time draws strangers together across the vast distances of space.

About the book
A “highly imaginative and utterly exhilarating” (Thrillist) debut that is “the best of what science fiction can be: a thought-provoking, heartrending story about the choices that define our lives” (Kirkus Reviews, Best Debut Fiction and Best Science Fiction & Fantasy of the Year).
FINALIST FOR THE LOCUS AWARD • NAMED ONE OF THE BEST BOOKS OF THE YEAR BY TORDOTCOM AND KIRKUS REVIEWS
A mysterious child lands in the care of a solitary woman, changing both of their lives forever.
I expected many things from this trip. I did not expect a family.
A ship captain, unfettered from time. A mute child, burdened with unimaginable power. A millennia-old woman, haunted by lifetimes of mistakes. In this captivating debut of connection across space and time, these outsiders will find in each other the things they lack: a place of love and belonging. A safe haven. A new beginning.
But the past hungers for them, and when it catches up, it threatens to tear this makeshift family apart.
Praise for The Vanished Birds
