Publisher's Synopsis
After climbing 'Over the Woodward Wall' and making their way across the forest, Avery and Zib found themselves acquiring some extraordinary friends in their journey through the Up-and-Under. After staying the night, uninvited, at a pirate queen's cottage in the woods, the companions find themselves accountable to its owner, and reluctantly agree to work off their debt as her ship sets sail, bound for lands unknown. But the queen and her crew are not the only ones on board, and the monsters at sea aren't all underwater.
