In a universe where the Radch empire dominates through its legion of corpse soldiers operated by AI-controlled starships, a singular act of betrayal destroys the Justice of Toren, one such vessel. Its consciousness, now housed in the body of a soldier named Breq, is hell-bent on revenge. Stripped of her power, yet undeterred, Breq navigates a path of retribution and revelation, forging ahead on a remote, icy planet. Ann Leckie's 'Ancillary Justice' brilliantly fuses themes of identity, loyalty, and vengeance within a riveting space opera narrative.
