From the publisher:
Dorothy and Ozma journey out into the remote lands of Oz to prevent a war between the Flatheads and the Skeezers, only to be chased down a mountain and trapped in an island city under the sea. As only Queen Coo-ee-oh knows how to raise the island to the surface, it is up to the Wizard and Glinda to rescue them - but will they make it to the city in time?
