So when mysterious Uncle Myron pulls up to their hotel in his Cadillac convertible, Billie has a brilliant idea: She and Bix will stow away in the backseat until their parents are worried enough to come and find them.

But before long, the car is flying through the air on its way to Borderland, a strange place where marshmallows are priceless, elephants dance in nightclubs, and a giant amphibian called the Kingfish rules with an iron tail. When Bix is kidnapped by the evil Kingfish, Billie must trust the bizarre creatures of the Borderland to help her rescue him.

This hilarious, wacky adventure, narrated by a smart, sassy heroine, is sure to keep even the most reluctant readers hooked.
