"It's the anniversary of daring Violet Parma's arrival in Eerie. But even after a year of searching, she still hasn't found her missing parents, and anxious Herbert Lemon has learned little else about why he washed up on the shore in a crate of lemons as a baby. What's more, the creators of the Anomalous Phenomena podcast have dropped anchor in town and are fishing around for secrets. Keeping ahead of the podcasters, Herbie and Violet set sail for the dangerous 'treasure island' where villain Sebastian Eels's twin sister mysteriously vanished years ago. Will they discover the heart of Eerie-on-Sea's mysteries, or will Herbie and Violet be the next to disappear?"--Provided by publisher.
