Under Witch Moon: Moon Shadow Series

Adriel should have known that with a werewolf, it never stopped with just one body. She would have gone to the police after witnessing Dolores' death, but she wasn't certain the killer she saw was responsible for the other murders. Besides, the police didn't believe in werewolves, and they weren't going to believe she was a witch either so what could she tell them? She kept her eyes and ears open while she tried to help her latest client escape the clutches of a voodoo witch, but things went from bad to worse when more bodies turned up. She was greatly relieved when she met White Feather, an undercover cop. Unfortunately, he wasn't convinced she was innocent of all wrong-doing. It was going to take every spell she knew and a few she hadn't tried to solve the murders and stay alive.
