Sex, Lies and Vampires

Take a flawed charmer named Nell, add a cursed Dark One called the Betrayer who has sold his own kind for centuries to a demon lord, and throw them together in a desperate attempt to save an innocent child...while along the way unentangling themselves from a Welsh knocker named Gigli who runs a house of ill repute for poltergeists, avoiding death by a revenge-minded vampire, and trying to convince a group of mummies that dead really does mean forever.
