Months after the killer of the Hunt has been locked up, a new string of deaths are pulsating through Bottle Island. This time, the police are quick to insist on simple causes: suicide, accident, unexplained heart attack. Anything except murder. But Luca Fern is seeing a pattern. The winter break has arrived and boatloads of tourists are settling on the island, creating a stream of faces that come and go. When a previous victim of the Hunt returns to Altswood and unveils a revelation, it is clear that the case has not been solved. Bottle Island has more secrets than truths, and Luca refuses to believe her paranoia has finally won over her. The Hunt has come to an end, but the killings have not.

After the chaos of two serial killers in Altswood, the island is finally at a calm. Luca Fern and Gabriel Kingston have become media darlings: the heroes of Bottle Island that every tourist wants a photo with. That is, until philanthropist Maire Reeve drops dead, and the two are accused of her murder. From power couple to homicidal duo, the stakes are high as the conspiracy threatens to destroy the very foundation of Bottle Island. As if that wasn't bad enough, Luca is receiving ominous notes asking her to solve a mystery that she has nothing do with. Or is a previous tragedy in Altswood the very cause of her current situation? As old secrets resurface and mix with new suspects, it is clear that this is not only a grudge against the present, but an avenging force from the past. Despite how much Luca wants to leave the Hunt behind and move forward, it all ends where it began: with the death of Beatrice Willis.
