A Science Fiction Novel | J. S. Dewes

About the Book

J. S. Dewes, author of The Last Watch and The Exiled Fleet, returns with another science fiction space opera, Rubicon, that melds elements of Scalzi’s Old Man’s War with Edge of Tomorrow.

Sergeant Adriene Valero wants to die.

She can’t.

After enduring a traumatic resurrection for the ninety-sixth time, Valero is reassigned to a special forces unit and outfitted with a cutting-edge virtual intelligence aid. They could turn the tide in the war against intelligent machines dedicated to the assimilation, or destruction, of humanity.

When her VI suddenly achieves sentience, Valero is drawn into the machinations of an enigmatic major who’s hell-bent on ending the war—by any means necessary.

“A fresh and forward-looking story about the costs of “forever” wars and the existential anxiety of artificial intelligence. … Many recent novels are also grappling with the ethics of AI, and Dewes’s novel shines in the field. Witty and readable, it features an endearing cast of characters and fast-paced action and will have broad appeal to fans of sci-fi beyond its MilSF genre.”—Library Journal

Dewes (the Divide series) continues to demonstrate a gift for superior hard sci-fi with a standalone outing that is simultaneously thoughtful and pulse-pounding. … Fans of smart military sci-fi will be riveted.“—Publishers Weekly

“Rubicon and the trauma in it feel terrifyingly real. I couldn’t look away.”—Mary Robinette Kowal, Hugo-award winning author of the Lady Astronaut series

Rubicon blew me away. Concept, characters, story, I loved it all. I can’t wait to see where J.S. Dewes takes this world next!”—Nalini Singh, New York Times Bestselling author of the Psy-Changeling and Guild Hunter series

Rubicon is non-stop military SF action with plenty of twists. I couldn’t put it down. J.S. Dewes has entered the military SF arena and firmly planted her flag as one of the best in the business today. ”—Michael Mammay, author of The Misfit Soldier

A high-octane blend of fast action, fun characters, and deep questions. In Rubicon, not even death can set you free.”—Megan O’Keefe, author of the Protectorate series
