When school psychologist Skye Denison stumbles over the body of pushy “Promfest” chairperson Annette Paine during a Halloween fundraiser, it looks like a clear-cut case of promicide. Annette was not the only prom mom desperate to see her daughter crowned queen—and her skirt-chasing hubby is no prince either. 

Skye’s anxious to investigate, but she keeps getting sidetracked by the overeager new social worker at school, and her current beau’s emotional distance. Still, one question haunts her: Annette Paine was wearing a witch costume identical to Skye’s, so which witch was the intended victim? Will Skye realize too late that finding this killer is a matter of her own life or death?
