Now, Alexander stands at the edge of a bottomless chasm. With a helpful shove from his foreign benefactor, he plunges into adventure.

Armed with his wits, he’ll set forth on the journey of a lifetime, recruited by aliens for a civil war in which the good side is bad, the bad side is good, and somehow, Alexander ends up square in the middle.

Choose your retailer
About the book
Earth faces annihilation. A tear in spacetime. An impossible choice.
Dr. Phil Bright's specialty was weather patterns, not existential threats. But when mysterious wormholes begin to appear near Saturn, carving massive, inexplicable gaps in the planet's rings, the impossible becomes terrifyingly real. Humanity is unprepared, grappling with a phenomenon that defies all known science.
Salvation arrives from an unknown galactic kingdom, heralded by a human professor with advanced technology and an offer of help. Yet, the price is steeper than any could imagine: Earth must surrender its sovereignty and pledge allegiance to King Manay XII, an artificial intelligence sovereign ruling trillions.
As Phil navigates a world of skeptical governments, alien wonders, and the truth behind the kingdom's ancient power, he's forced to confront the ultimate dilemma: sacrifice humanity's freedom for survival, or watch the planet he loves be consumed by cosmic ruin.

The Risen Empire
Scott Westerfeld
Sci-Fi · Galactic Empire · Hard Sci-Fi · Space Opera
Our take
Called “exceptionally smart and empathetic” by Publishers Weekly, this space opera follows Captain Laurent Zai as he attempts to rescue the Child Empress from the Rix, machine-augmented rebels challenging an immortal emperor's rule. Meanwhile, Senator Nara Oxham faces political conflict that could determine the empire's future. Ideal for readers who enjoy military science fiction, interstellar politics, and advanced technology.
Choose your retailer
About the book
"Westerfeld's blend of traditional space opera and cutting-edge speculation makes this a truly twenty-first-century SF novel." —Karl Schroeder, author of Pirate Sun
The undead Emperor has ruled his mighty interstellar empire of eighty human worlds for sixteen hundred years. Because he can grant a form of eternal life, creating an elite known as the Risen, his power has been absolute. He and his sister, the Child Empress, who is eternally a little girl, are worshiped as living gods. No one can touch them.
Not until the Rix, machine-augmented humans who worship very different gods: AI compound minds of planetary extent. The Rix are cool, relentless fanatics, and their only goal is to propagate such AIs throughout the galaxy. They seek to end, by any means necessary, the Emperor's prolonged tyranny of one and supplant it with an eternal cybernetic dynasty of their own. They begin by taking the Child Empress hostage. Captain Laurent Zai of the Imperial Frigate Lynx is tasked with her rescue.
Separated by light-years, bound by an unlikely love, Zai and pacifist senator Nara Oxham must each in their own way, face the challenge of the Rix, and they each will hold the fate of the empire in their hands. The Risen Empire is the first great space opera of the twenty-first century.
"In the tradition of Isaac Asimov's Foundation series and Frank Herbert's Dune books." —The New York Times
"Confirms the buzz that space opera is one of the most exciting branches of current SF." —Publishers Weekly (starred review)

Choose your retailer
About the book
Chase is finally coming to understand just what being Prince Chase means, and what becoming emperor to the Solarian Empire will mean as well. He's getting better at the job every day, now if only he could just bring himself to tell Captain Witner and the other members of the command staff that he really is a prince, and not the fraud they all believe he is.
Another thing he is starting to learn more about is Imperial politics and the kinds of things princes and emperors are known for, as well as expected to do. He's also discovering that there are a lot of people who still believe he's a fraud, because of Neill's efforts at proclaiming him as such. Of course his criminal background isn't helping him much there.
What is helping him however are some of the people he's discovering, and some of the things he's learning about his family from them. There are still a good many surprises in store for Chase. Hopefully none of those surprises will end up killing him.
