After learning that she comes from a family of witches—and adopting a familiar named Alistair—artist Annabelle Britton has made beautiful Portsmouth, New Hampshire, her home. Together with her coven, this good witch is trying to put a stop to magic and murder most foul.
When Anna takes Alistair to see local veterinarian Ramona Forsythe, they meet the most famous cat in town: Ruby the Attitude Cat, spokes-feline for a pet food brand. But then Ramona turns up dead, and Ruby goes missing. It seems like the murderer used magical means, so it’s up to Anna and Alistair to catch a killer and cat-napper as only a canny cat can.
