Pirate Emperor-Wave walkers book 2

Grade 6–9—This title continues the story begun in Pirate Curse, set in a Caribbean fantasy world. Fourteen-year-old Jolly and Munk, the last two remaining pirate polliwogs, have the magical ability to walk on water. They may be the only ones able to save the floating coral city of Aelenium from the Maelstrom, but to do so, they will need to dive six miles down into the ocean to close the source of the ancient malevolent force and thereby prevent the opening of a gate to another world, the Mare Tenebrosum.
