The close-knit community of Kinton Bay is shocked when fifteen-year-old Siena Britton makes a grisly discovery in the national park. Siena believes it's a skull from the town's violent colonial past and posts a video which hits the news headlines. But her parents, Meri and Rollo, think the skull is related to their teenage parties in the Killing Cave back in the 1990s. And a school mate who went missing then. None of them foresees the dangers that discovery will create for their family. The dangers of past deceits, silences and lies that have never been resolved.
