A wonderful friendship has been injured and the three friends are holding grudges against each other. The grudges are put on hold when Nat, Teddy’s younger sister, comes up missing. I love the character development! The author does a great job bringing her characters to life. Ben’s colorful personality has grown from his dysfunctional family life full of contradictions and hypocrisy, but he’s loyal to his best friends, who are his cousin Amy and their mutual friend Teddy. Nat is precious and precocious and adorable. Amy is hounded by her mother and her extreme expectations and Teddy and Nat live with their single mother in a trailer on Ben and Amy’s grandparents’ property. The three friends work together to try to figure out what happened to Nat. The timeline alternates between two summers and the changes that occurred in their relationships. The police believe that Nat drowned but the three friends know she would have never gone into the water alone. Nat was terrified of swimming after she almost drowned years earlier. As Ben, Teddy and Amy search for clues, they stumble across a trophy box from a possible serial killer. Intensity and suspense amid a large amount of dysfunction kept me reading into the wee hours of the night, 5 stars!
