When her mother and brother are murdered, young noblewoman Accala Viridius cries out for vengeance. But the empire is being torn apart by a galactic civil war, and her demands fall on deaf ears. Undeterred, Accala sacrifices privilege and status to train as a common gladiator. Mastering the one weapon available to her--a razor-sharp discus that always returns when thrown--she enters the deadly imperial games, the only arena where she can face her enemies. But Fortune's wheel grants Accala no favors--the emperor decrees that the games will be used to settle the civil war, the indigenous lifeforms of the arena-world are staging a violent revolt, and Accala finds herself drugged, cast into slavery and forced to fight on the side of the men she set out to kill. Set in a future Rome that never fell, but instead expanded to become a galaxy-spanning empire, Accala's struggle to survive and exact her revenge will take her on a dark journey that will cost her more than she ever imagined.
