When a bloodthirsty power grab on Earth results in the murder of her entire family, wealthy socialite Cat Carletto is forced into hiding. On the run from the ruthless Empress Ophelia, and seeking revenge against the woman who destroyed her life, Cat enlists in the Legion—an elite cyborg fighting force made up of society's most dangerous misfits. On the battlefield, Cat Carletto vanishes, and in her place stands Legion recruit Andromeda McKee. As she rises through the ranks, Andromeda has one mission: bring down Empress Ophelia—or die trying.
