"It's Midwinter again in Eerie-on-Sea, when legend claims the terrifying Malamander emerges to hunt--and search for its long-lost mate. It's the anniversary of daring Violet Parma's arrival in Eerie; a year later, she still hasn't found her missing parents, just as anxious Herbert Lemon has learned little else about why he washed up on the shore in a crate of lemons. What's more, the creators of the Anomalous Phenomena podcast have dropped anchor in town and are fishing around for Eerie secrets. Keeping ahead of the podcasters, Herbie and Violet set sail for the dangerous "Treasure Island," where villain Sebastian Eel's own 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? Like a visit to an old boardwalk arcade, this conclusion to the spooky, fantastical series will leave readers shivering with fright and delight. In this fifth and final tale, the arrival of a team of cryptozoologists sets off a series of events that could reveal the deepest secrets of Eerie-on-Sea--and the truth about shipwrecked orphan Herbert Lemon." -- Provided by publisher.
