A therapist must face her own worst fear—one of her patients is a serial killer. Dani Rycroft suspects someone close to her has a dark secret. In the confidential setting of therapy, her patients share their anxieties and fears. Now, with a string of murders in town putting her on edge, Dani’s own worries come close to eclipsing her patients’. In each case, the pattern is the same: parents killed while their children sleep blissfully unaware in their beds. Her best friend, Detective Tami Sloan, is the only person she has confided in. Dani believes that there’s still a secret one patient has yet to share. But which one? Behind a familiar face is a stranger who’ll do anything to hide their worst compulsions. The anxiety brings Dani to her own therapist’s office, seeking counsel and comfort. But what is she willing to risk, and how much closer must she get, to stop them?
