“Don't worry,” said Princess Leora's father just before he left for the tournament. “If anything goes wrong, release a bunch of balloons from the castle tower. Wherever I am, I will see them and come home right away.” Now, something is wrong—very wrong. Princess Leora's grumpy uncle, the Archduke, wants to be king, and the very first thing he does is pop every balloon in the kingdom. Princess Leora is afraid, but she doesn't give up. If she can find just one whole balloon, the kingdom will be saved!
