Fifth Grave Past the Light

Charley is trying to figure out her relationship to the sexy Reyes who is living next door and is the son of Satan. Charley is a grim reaper helping souls cross to the other side while working as a private eye. Blond female ghosts keep popping up in her apartment and she knows somehow this is a serial killer issue. She maintains her flippant attitude all during the book which sometimes gets a little annoying. I know its a defense mechanism but sometimes it is a bit much. But I still enjoyed the story very much.
