Blackgate House, Masquerade Ball. At eleven o'clock the daughter of the owner of the estate, the young Evelyn Hardcastle, will be killed. Again. This horrible cycle cannot be broken until one of those present names the killer.

Every day Aiden Bishop will wake up in the body of one of the guests with the eternal question: who killed Evelyn Hardcastle? Seven days, seven warnings. Maybe, being in someone else's body, Aiden will finally be able to expose the killer until the next shot is fired and Evelyn's life ends ... Again.
