About the book
His Name Opened Doors. His Honor Closed Them.
Instead of joining the ranks of the political elite, Innes Kingsford chose to become an ensign in the navy, making him the black sheep of one of the greatest families in the Republic of Concordia. That wasn't enough for his family to keep from using him as a pawn. When his assignment to the strike cruiser Illustrious is orchestrated by his father as part of a political scheme, Innes finds himself stationed at remote Shiro Station under the command of Lieutenant Kyle Wexler, a member of his family's greatest house rivals. Things only get more complex as Innes discovers conspiracy, criminal enterprises, and possible interstellar war converging around him.
Caught between his oath to the navy and his father's machinations, can Innes manage to do his duty without losing his commission or his life?

About the book
"The successor to The Risen Empire is just as fine a rip-roaring space opera"—from the #1 New York Times–bestselling author (Booklist).
Captain Laurent Zai of the Imperial frigate Lynx is a walking dead man. Unjustly held responsible for the death of the Child Empress, sister of the immortal Emperor, Zai has been sent to fight an unwinnable battle. The Lynx must stop a vastly superior Rix ship from reaching the planet Legis, a suicide mission that will almost certainly end in oblivion for Captain Zai and his crew.
On the planet Legis below, a Rix compound mind—a massive emergent AI formed from every computer on the planet—has been isolated by their Imperial blockade. But the mind has guided a lone Rix commando, Herd, to the planet's frozen north, and will soon order a desperate attempt to seize a polar communications array and break the blockade.
Ten light-years away, Captain Zai's true love, the psychic (some say mad) Senator Nara Oxham is engaged in a deadly game of political intrigue. From her position on the Emperor's War Council, Senator Oxham must find a way to forestall the Emperor's final solution if the blockade is broken: a nuclear strike to destroy the compound mind, which will also kill millions of Imperial citizens. She suspects that the Emperor has a hidden weakness discovered by the mind, a secret so dangerous to his immortal dynasty that to prevent its discovery the Emperor is willing to countenance the ultimate crime . . .
The killing of worlds.

About the book
Nebula-winning author of the Alex Benedict series:A woman steals a starship to find her long-lost clone-sister in a "masterly" novel of first contact (Library Journal).
We are alone. That is the verdict, after centuries of Search for Extra-Terrestrial Intelligence missions and space exploration. The only living things in the Universe are found on the Nine Worlds settled from Earth, and the starships that knit them together. Or so it's believed, until Dr. Kimberly Brandywine sets out to find what happened to her clone-sister Emily, who, after the final unsuccessful manned SETI expedition, disappeared along with the rest of her ship's crew.
Following a few ominous clues, Kim discovers the ship's log was faked. Something happened out there in the darkness between the stars, and she's prepared to go to any length to find answers. Even if it means giving up her career . . . stealing a starship . . . losing her lover. Kim is about to discover the truth about her sister—and about more than she ever dared imagine.

About the book
The unfinished sci-fi masterpiece by the author of Stranger in a Strange Land—completed by the Hugo Award–winning author of The Stardance Trilogy.
Joel Johnston has found the love of his life in Jinny Hamilton. Life would be perfect if only he earned enough money to support a family. But now that Jinny knows his love is true, she reveals an incredible secret: she is really Jinny Conrad, granddaughter of Richard Conrad, the wealthiest man in the solar system. And now that Joel proven his love for Jinny, her family has a plan for him.
Joel is to be groomed for a place in the vast Conrad empire and sire a dynasty to carry on the family business. Most men would jump at the opportunity. But to Jinny's surprise, and even his own, Joel turns down her generous offer and sets off on the mother of all benders.
When he wakes up on a colony ship heading into space, he decides it's time to forget Jinny and make a life among the stars. But his plans—and the plans of billions of others—are shattered by a cosmic cataclysm so devastating it will take all of humanity's strength and ingenuity just to survive.
When an outline for Variable Star was found among Robert A. Heinlein's papers, Spider Robinson was commissioned to complete the novel. The result is a thrilling new work of science fiction from two of the genre's greatest minds.

About the book
New York Times Notable Book of the Year
Explore a universe where genetic mutations allow individuals to traverse the stars in this action-packed space opera for fans of Frank Herbert and Samuel R. Delaney!
It is the second stage of human colonization—the first age, humanity’s initial attempt to people the stars, ended in disaster when it was discovered that Earth’s original superluminal drive did permanent genetic damage to all who used it—mutating Earth’s far-flung colonists in mind and body.
Now, one of Earth’s first colonies has given humanity back the stars, but at a high price—a monopoly over all human commerce. And when a satellite in Earth’s outer orbit is viciously attacked by corporate raiders, an unusual young woman flees to a ship bound for the Up-and-Out.
But her narrow escape does not mean safety. For speeding across the galaxy pursued by ruthless, but unknown adversaries, this young woman will discover a secret which is buried deep inside her psyche—a revelation the universe may not be ready to face . . .

About the book
When the Jedi Order falls, an Inquisitor rises.
Padawan Iskat Akaris has dedicated her life to traveling the galaxy alongside her master, learning the ways of the Force to become a good Jedi. Despite Iskat’s dedication, peace and control have remained elusive, and with each setback, she feels her fellow Jedi grow more distrustful of her. Already uncertain about her future in the Jedi Order, Iskat faces tragedy when her master is killed and the Clone Wars engulf the galaxy in chaos.
Now a general on the front lines contributing to that chaos, she is often reminded: Trust in your training. Trust in the wisdom of the Council. Trust in the Force. Yet as the shadows of doubt take hold, Iskat begins to ask questions that no Jedi is supposed to ask. Questions about her own unknown past. Questions the Jedi Masters would consider dangerous.
As the years pass and the war endures, Iskat’s faith in the Jedi wanes. If they would grant her more freedom, she is certain she could do more to protect the galaxy. If they would trust her with more knowledge, she could finally cast aside the shadows that have begun to consume her. When the Jedi Order finally falls, Iskat seizes the chance to forge a path of her own. She embraces the salvation of Order 66.
As an Inquisitor, Iskat finds the freedom she has always craved: to question, to want. And with each strike of her red blade, Iskat moves closer to claiming her new destiny in the Force—whatever the cost.

About the book
"This is hard SF at its best. . . Schroeder belongs to a dynasty that includes Benford, Vinge and Egan." —Stephen Baxter
Author and professional futurist Karl Schroeder, whose novels Ventus and Permanence have established him as a groundbreaking visionary in hard science fiction, extends his imagination into Larry Niven territory, returning to the same distant future in which Ventus was set, but employing a broader canvas, to tell the story of Teven Coronal, a ringworld with a huge multiplicity of human civilizations.
Brilliant but troubled Livia Kodaly is Teven's only hope against invaders both human and superhuman who would destroy its fragile ecologies and human diversity.
Filled with action, ideas, and intellectual energy, Lady of Mazes is the hard SF novel of the year.
"With Lady of Mazes, Schroeder gives us another novel of marvelous insight—brightest glimpses of where our technology of communication and computation may be taking us." —Vernor Vinge
"A complete original . . . it's the most thought-provoking and interesting work of hard SF that I've read in the past year, and it deserves to be recognized as belonging to the cutting edge of the new far future in SF." —Charles Stross
"An astonishing saga. One helluva read!" —Charles Harness
"Karl Schroeder has always had a knack for intelligent and provocative thought experiments, disguised as space opera. Now he ups the ante with a fascinating riff on consensual (and conflicting) realities. Lady of Mazes contains more cool ideas than Ventus and Permanence combined." —Peter Watts

About the book
A 2026 Philip K. Dick Award Finalist
A debut science fiction novel by National Book Award–winning writer William Alexander, this story of found family follows a planetary courier training adolescent androids in a solar system grappling with interplanetary conflict after a devastating explosion on Earth’s moon.
Captain Tova Lir chose a life as a courier rather than get involved in her family’s illustrious business in politics. Set in humanity’s far future, hiring a planetary courier is essential for delivering private messages across the stars.
Encouraged by friends, Tova begins mentoring baby bots, juvenile AI who are developmentally in their teens, and trains them how to interact within society essentially becoming their foster mom. Her latest charge, Agatha Panza von Sparkles, named herself on their first run from Luna to Phoebe station. But on their return, they encounter a derelict spaceship and a lurking assassin, igniting a thrilling chase across the solar system.
Tova and Agatha’s daring actions leave Agatha’s mind vulnerable, relying on Tova’s former AI pupils for help. As Tova starts gathering her scattered family around her, she is chased through the solar system by forces who want her captured and her family erased. This debut science fiction novel by National Book Award–winning author William Alexander is a must-read for fans of Becky Chambers and Ursula K. Le Guin. Lovers of poignant science fiction, where the bonds of found family, the evolution of AI, and the building distrust of centuries of bias, come together in this visionary look at humanity’s future.

About the book
Ethan Cross expected second shift at Meridian Industrial to end the way it always did—oil-stained hands, clock out, go home.
Then something impossible shows up behind the plant. It isn’t on any schedule. It isn’t on any radar. And it definitely isn’t human.
Ethan makes one mistake, he gets close.
That’s when his ordinary life ends. Whatever is sitting in the dark isn’t debris or a prank—it’s a machine built for a purpose, and it didn’t arrive by accident. Ethan doesn’t know what it wants, or who it belongs to, but he knows this much: the moment he touched it, a countdown started.
Some doors open to freedom. Some open to trouble.
This one opens to the stars.
