On a warm Fourth of July night in Duck Lake, Michigan, the Wentworths' world shattered. As fireworks lit up the sky, Richie and Olive's four-year-old daughter was pulled from the dark waters of the lake, her death ruled an accidental drowning. Seven years later, Olive still lives in the shadow of that night. Her grief is numbed by pills, while Richie, a celebrated oncologist, thrives in the spotlight of his career. But as another Fourth of July celebration approaches, the lake yields another body, and the chilling discovery suggests that the tragedy from years ago may not have been an accident after all. Determined to uncover the truth, Olive digs beneath the polished surface of her picture-perfect neighborhood, where Midwestern smiles conceal dangerous secrets. Each revelation threatens to unravel not only Richie's hard-won reputation but also the very foundation of their tight-knit community. In a town where appearances are everything, Olive must confront the terrifying question: who would take the life of a child, and how far will they go to keep their sins submerged?
