A heartless murder for Valentine's Day — Melanie Cooper and Angie DeLaura must be doing something right with their Fairy Tale Cupcakes bakery. Their business rival, Olivia Puckett, is parading up and down the sidewalk dressed as a giant cupcake to steal customers. With Valentine's Day just around the corner, she's clearly feeling desperate.

Unfortunately, she's not the only desperate one in Scottsdale, Arizona. Someone has iced Baxter Malloy on his first date with Mel's mother. Her mom had been hoping for someone drop-dead gorgeous -- but not literally. Now she's a suspect, and Mel and Angie need to find time between frosting Kiss Me Cupcakes to dig into Malloy's shady past and discover who served him his just desserts.
