There are two peoples living in the city of Ursa: the Cerels and the Travesters. Traversters move freely and enjoy a fine quality of live. Cerel men are kept in wild camps and the women are no longer allowed to have children. The Director presides over all with an iron fist. Fifteen-year-old Leho can't remember a time when Cerels lived without fear in Ursa. His parents once tried to organise an uprising - his mother was blinded, and his father was taken away. But now his world is changing. Revolution is coming. People will die. Will Leho be able to save his family?
