Dani comes from the richest, most famous Black family in Texas and has everything a girl could want. So why does she keep using drugs and engaging in other self-destructive behavior?

Camila's Colombian American family doesn't have much, but she knows exactly what she wants out of life and works her ass off to get it. So why does she keep failing, and why does she self-harm every time she does?

When Dani and Camila find themselves rooming together at Peach Tree Hills, a treatment facility in beautiful rural Georgia, they initially think they'll never get along--and they'll never get better. But then they find a mysterious music box filled with letters from a former resident of PTH, and together they set out to solve the mystery of who this girl was . . . and who she's become. The investigation will bring them closer, and what they find at the end might just bring them hope.
