An easy horror read with a new take on the vampire and werewolf origin story. While demons slowly possess people in a hospital, our PhD student heroine Ann is trying to track down her on-again off-again Dr boyfriend with no luck, while there she meets off-duty traffic cop Matt. Also arriving at the same time is Joseph Miller, a supernaturally powered man, with a very cheery personality, who is reborn each time demons start getting out of hand on earth. Together they try to figure what the hell is going on at the hospital. A good sprinkling of humour and quick action kept me entertained right to the end.
