Ballad for a mad girl

Seventeen-year-old Grace Foley is a risk-taker, and as part of the long-running feud between two schools, accepts a challenge to walk the pipe. That night she experiences something she can't explain, and becomes haunted by voices and visions. She's drawn deeper into a twenty-year-old mystery surrounding missing girl Hannah Holt, and can no longer tell what's real or imagined. She is losing herself, and her friends don't understand.
