I found this older book in a used book store.  I really loved her other books and this was not a disappointment.  Sylvie is a witch in Louisiana, owner of small mystic shop.The new guy in town pulls up in a hearse looking for books on witch spells.  He's opening a haunted house.  About the same time he shows up.  There are killings at the full moon and looks like theirs a werewolf in town.
