Thirteen-year-old Kim Reid will never forget the summer of 1979. When she isn't thinking about boys, makeup, and starting high school in the fall, she's busy taking care of her little sister while her single mom works as a cop. By midsummer, the discovery of two murdered teens along a quiet Atlanta road changes everything.
School starts again, but having fewer kids on the streets doesn't stop the killer. More children disappear, silently vanishing from the skating rink and sidewalks she regularly visits, and Kim soon learns there is no place safe. When her mother is assigned to a special task force created to solve the murders, bringing her work home and becoming preoccupied with her increasingly high-profile job, Kim feels life unraveling. It becomes increasingly difficult to straddle two worlds: her neighborhood not far from where several victims are found, and her wealthy private school where she feels removed from the danger. Teetering on the brink between girl and woman, Kim is torn between fitting in and finding her own voice; between becoming strong and clinging to the last traces of her childhood.
