Deep in a national park on the east coast of Tasmania, the Bay of Fires is an idyllic holiday community. There are no more than a dozen shacks beside the lagoon - and secrets are hard to keep; the intimacy of other people's lives is their nourishment. The fact that Sarah Avery has returned, having left her boyfriend and her job, is cause for gossip in itself. Then, the bikini-clad body of a young girl is found washed up on the beach a year after another teenage girl went missing. Journalist Hall Flynn is sent to the coast to investigate, and all too quickly the close-knit community turns in on itself.
