"Melanie Cooper has zero interest in catering her fifteen-year high school reunion, but Angie insists it's only right that they bask in the success of Fairy Tale Cupcakes. Everything is going better than expected until Cassidy Havers, resident mean girl and Mel's high school nemesis, picks a fight. No longer willing to put up with Cassidy's bullying, Mel is ready to tell the former homecoming queen to shut her piehole and call it a night. But as Mel and Joe prepare to depart, Cassidy is found dead in the girl's bathroom, next to a note written in lipstick that points right to Mel."-- Provided by publisher.
