If you want a genre bender title, then maybe--

Writer and college professor Justin Gustainis has a new paperback series which may dovetail in the hot popularity of the supernatural and fantasy (no vampires to my knowledge though). His titles feature supernatural investigator Quincey Morris and his partner white witch Libby Chastain. The first book is Black Magic Woman and I spied it in the new fiction book area of the library a few days ago.

Black Magic Woman tells of the investigative duo helping a family plagued by a curse which may date back to the Salem Witch Trials. They follow a trial through hazardous occult communities across the country--including San Francisco, New York and New Orleans--to resolve their case.

Although these works are a genre bender more as fantasy and thriller with all the action, Woman and the follow-up title (Evil Ways according to the author's website), I suspect it could have some strong appeal for those looking a bizarre sort of mystery.
