Whiskey Witches by F.J. Blooding

A string of occult murders. A witch with no powers. The fun never ends. Detective Paige Whiskey is the only Whiskey Witch without powers. Or is she? When she’s called to St. Francisville, Louisiana to solve a series of occult murders, her world is forever changed. She discovers that demons are real and uncovers a secret about her past that could destroy her family. Together with demon hunter, Dexx Colt, her kitchen-witch grandmother, and her paranormal investigator brother-in-law, they unravel a conspiracy far bigger than a few simple murders. Paige is the demon summoner. And she’s the key to a much larger plan.
