Everly isn't like most girls her age. She has a monster. Not one you can see or feel but a darkness under her skin. Just beneath the flesh. Waiting come out. One night after her date at the bar with a college football star her life changes forever. In a sanatorium she must find out the secrets luring her in the walls and what her mysterious stranger and the dreamy Dr. Reynolds are up to. All while fighting the urge for blood.
