To help save her family's floundering Colorado bookstore, Emma Starrs stages a mystery-themed dinner party for her wealthy friend Tabitha Baxter. It's a delightful evening—until Tabitha's husband winds up murdered, and Emma and her aunt Nora, a famous mystery writer, become suspects. Author Calliope Nightfall asks Emma to throw a Poe-inspired bash for the launch of her new book, but when another crime ensues, Emma and her aunt will need to become sleuths very quickly or risk becoming felons.
