Ancillary Justice by Ann Leckie

Winner of the Hugo, Nebula, and Arthur C. Clarke Awards: This record-breaking novel follows a warship trapped in a human body on a quest for revenge. A must read for fans of Ursula K. Le Guin and James S. A. Corey. 

On a remote, icy planet, the soldier known as Breq is drawing closer to completing her quest.

Once, she was the Justice of Toren—a colossal starship with an artificial intelligence linking thousands of soldiers in the service of the Radch, the empire that conquered the galaxy.

Now, an act of treachery has ripped it all away, leaving her with one fragile human body, unanswered questions, and a burning desire for vengeance. (Amazon)
