From the publisher:
It all begins when Peter Duck, an elderly sailor once marooned on an island in the Caribbean, tells a tale to the Swallows and Amazons. It's a tale of buried treasure and, unfortunately, when the kids set sail to find it, the pirate Jake, captain of the Viper, follows.
Across the Atlantic Ocean, through fog, threats from pirate Jake, a hurricane, and an earthquake once they land, the Swallows and Amazons have to find the treasure, evade the pirates, and return safely home to England.
