The Thirteenth Princess by Diane Zahler (published by HarperCollins, August 25, 2009)
Zita's not just any servant girl: she's a princess-the thirteenth daughter of a king who wanted only sons and banished her to the servants' quarters to work in the castle's kitchen. Then, after Zita's twelfth birthday, her royal sisters all fall mysteriously ill. The only clue is their strangely worn and tattered shoes. With the help of her friends-Breckin the stable boy, Babette the witch, and Milek the soldier-Zita follows her bewitched sisters into a magical world of endless dancing and dreams. Something sinister is afoot-and Zita must find the source of the enchantment and break the curse, or the twelve princesses will surely dance to their deaths.
With a mesmerizing voice and delightful imagination, Diana Zahler delivers a dazzling retelling of "The Twelve Dancing Princesses." Zita is the spunky and unforgettable heroine that young girls will love.
