'At fourteen, Katia is chosen to serve at the Sisterhood's temple in Tenebrak. But violent Discord engulfs the planet threatening the 20,000-year-old Sisterhood's existence. In a satellite far above Tenebrak, Davred, brilliant xeno-anthropologist, studies the Sisterhood, and risks everything by deciding to help them. But neither Davred nor the Sisters know all the secrets of this mysterious planet.'
