The rescue should have been routine: a lone survivor found drifting miles offshore. But the woman they pull from the waves isn't wearing a lifejacket. She isn't injured. She isn't afraid. And she knows Mara Parker's name before Mara even speaks.

By morning, half the town is talking. By evening, the woman has vanished from the hospital and begun appearing at the harbour mouth, staring out to sea as though waiting for something to rise.

Mara tries to ignore the unease tightening around Looe — until the woman mentions her father. Ben Parker died years ago, but she remembers him. She remembers what he brought back. And she remembers what followed.

The tide is turning. The voices are rising. And Mara is about to learn that some rescues should never happen.
