Pretty Dead Queens - Alexa Donne

After the death of her mom (screw cancer), seventeen-year-old Cecelia Ellis goes to live with her estranged grandmother, a celebrated author whose Victorian mansion is as creepy as the murder mysteries she writes. On the surface, life is utterly ordinary in the California coastal town . . . until the homecoming queen is murdered. And she's not Seaview's first pretty dead queen. With a copycat killer on the loose, Cecelia throws herself into the investigation, determined to crack the case like the heroines in her grandmother's books. But the more Cecelia digs into the town's secrets, the more she worries that her own mystery might not have a storybook ending.
