A bestselling Caldecott Honor artist and legendary author team up!

A publishing event! Florence Parry Heide, author of such classics as the Shrinking of Treehorn, and Lane Smith, recipient of a slew of awards, have created an unforgettable princess sure to charm and delight young readers.

Princess Hyacinth has a problem: she floats. And so the king and queen have pebbles sewn into the tops of her socks, and force her to wear a crown encrusted with the heaviest jewels in the kingdom to keep her earthbound. But one day, Hyacinth comes across a balloon man and decides to take off all her princess clothes, grab a balloon, and float free. Hooray! Alas, when the balloon man lets go of the string . . . off she goes. Luckily, there is a kite and a boy named Boy to save her.
