One hot summer’s evening, ten-year-old Piper Chase went for a bike ride. She never came home… Piper cycles off one hot Oklahoma evening for a sleepover with her new friend Miley from summer camp. But when she doesn’t come home, her grandparents raise the alarm. Their little angel is missing, last seen on her pink bicycle, heading towards the dark woods on Black Heart Lane. Detective Kimberley King knows that the first twenty-four hours in a missing child investigation are the most critical, but with no witnesses, and darkness falling in the small town of Dead Woman Crossing, she begins to fear the worst. She longs to find the little girl with wide blue eyes and an infectious smile, but when her team discovers Piper’s body in a woodland clearing, lying on a bed of moss, something inside her dies. In a town where people leave their doors unlocked, Kimberley is terrified that another little girl might be snatched, and that night she holds her own daughter tighter. Desperate to find the monster who took the life of an innocent child, Kimberley chases down all the leads she has. The summer camp counsellor, who got too close to Piper and Miley and lost his job. Piper’s shifty uncle, who arrived back in town the day she disappeared… Then she gets a call that chills her to the bone. Miley has gone missing. Has the killer who stole one little angel just taken another?
