Everyone knows seventeen-year-old Grace Foley is a bit mad. She's a prankster and a risk-taker, not afraid of anything - except losing. As part of the long-running feud between two local schools in Swanston, Grace accepts a challenge to walk the pipe. That night she experiences something she can't explain. As she's drawn deeper into a twenty-year-old mystery surrounding missing girl Hannah Holt, the thin veil between this world and the next begins to slip. She can no longer tell what's real or imagined - all she knows is the ghosts of Swanston, including that of her own mother, are restless.
