Six years ago, Evie Cormac was found hiding in a secret room in the aftermath of a brutal murder. But nobody has ever discovered her real name or where she came from, because everybody who tries ends up dead. Forensic psychologist Cyrus Haven believes the truth will set Evie free. Ignoring her warnings, he begins to dig into her past, only to disturb a hornet's nest of corrupt and powerful people, who have been waiting to find Evie - the final witness to their crimes. Unbeknownst to him, Cyrus is leading them straight to Evie.
