Book Two of the Japapa trilogy resumes with the three teens searching for treasure from a Spanish galleon that allegedly sank off Fortune Island. At the same time, the demon Baka continues to seek revenge against them and Sharkman.

The demon sends a horrific hurricane to the Bahamas during which he throws Sharkman back to Pompeii just prior to the eruption of Mount Vesuvius and hurls the teens back to a time where Japapa has assumed the body of the pirate Black Caesar and is charged with torturing them on behalf of Baka.

The intended revenge includes having the boys sold as slaves and Simone becoming part of Blackbeard's harem. While Sharkman and the teens face a number of challenges, Mama Atabei enlists the help of a wizard called The Seer who is able to transport himself and her back in time to find and rescue the teens and Sharkman. Will they be successful?
