Untaming Delilah (Destined Mate 1) (Destined Mates) by Ashlynn Monroe - Romance>Paranormal/Horror
Delilah's rare medical disorder has made her a virtual prisoner of her guardian, Doctor Peter Amun, and the drug he created to keep her alive. She spends much of her time alone, buried in Gothic romance novels. But she often feels a strange connection -- as if someone's watching her.
Mick's uncle has kept him locked in the old dungeon-like basement of the hospital since he was a teenager, but his consciousness can escape the hell of his existence for a time as he sees thru the eyes of the one woman he cannot live without. Delilah stirs what's left of the man left inside the beast Mick has become. Delilah's blood is an addiction he cannot escape -- his body burns every time he feeds.
When a stranger joins forces with them to put a stop to Doctor Amun's experiments, Mick is forced to accept a bond he doesn't fully understand. The need to possess Delilah controls Mick, but the urge to protect her from what he has become fills him with bitter rage. He knows he'll do whatever it takes to keep her safe.
