Summer is a hectic time of the year for Annie Darling. Sun and scorching temperatures never fail to bring swarms of tourists to her mystery bookstore, Death on Demand. But Annie still finds time to enjoy herself. The Broward's Rock Fourth of July dance is just around the corner, and the island is buzzing with excitement—Shell Hurst included. Shell is the kind of woman wives hate—and most of them wish she would just disappear. But when she does, Annie can't help but feel like someone should be looking for her. The residents of Broward's Rock grow uneasy when a second islander mysteriously disappears. Annie and her husband, Max, soon find themselves following a twisted trail marked by blackmail, betrayal, and adultery.
