Acacia Sheridan is a private detective with a special gift for perceiving the supernatural. When a local coven of urban witches mistakenly summons a malevolent spirit, they look to Acacia to help track him down. Inconsistencies in the witches' story make Acacia begin to suspect they're not telling her everything--and then the murders start.

With her assistant Oliver stressing over a past bad experience with witches, a demon on the loose, and a nosy police detective wanting to know too much, Acacia's up to her elbows in supernatural trouble in this fourth installment of the Olympia Investigations series.
