For nine-year-old Wendy, the summer of 1969 will never be forgotten.

Local kids have always told stories about the eerie wood on the outskirts of the village, and Wendy knows for sure that some of them are true. Now the school holidays have started and she's going to the wood again with Anna and Sam, but they soon become convinced that someone is trying to frighten them off.

When a terrible event rocks the coastal community, the young friends can't help thinking there must be a connection between the incident, the tales they've heard, and the strange happenings they've begun to witness. As glimpses of a darker world threaten their carefree existence, they feel compelled to search out the underlying truth.
