Fishville by Afsaneh Gray

The story starts when a young man named Jared takes to the sea in swimming gear but never starts swimming… His death, which follows on from the unexpected sale of his parents’ house, throws the community into chaos. When the daughter of the man who bought Jared’s house arrives in Saltwell and finds a severed foot washed up at her feet, she and the daughter of the ‘second homers’ decide to investigate what drove Jared into the sea. They uncover a local myth about an underwater community – did Jared believe the myth? Then, ‘Jared’ starts posting messages, asking his friends to join him. With the new girl’s father spending more and more time in the sea, and the myth gaining traction, the young people must figure out what’s going on before anybody else is lost to a vengeful ocean…
