Ancillary Justice

On a distant icy planet, the soldier Breq is close to completing her quest for vengeance. She was once the Justice of Toren—a colossal starship with an artificial intelligence linking thousands of soldiers in the service of the Radch, an empire that conquered the galaxy. But on what was meant to be her final mission, she betrayed her orders, and now has only one fragile human body and unanswered questions.
