"Eighteen-year-old Trinity Marrow, who is losing her sight, has a well-kept secret. She can see and talk to the dead and must remain in a compound that is guarded by Wardens who are shape-shifting gargoyles. They must protect her from demons who want to capture her to take on her special powers. However, a new threat arrives, and Trinity joins forces with Zayne, a Warden from another clan, in order to save her family."--,Publisher's description.
