Are you growing tired of royal balls and boring banquets with visiting kings and princes? Do you long to escape the confines of the palace and find yourself in a completely new place, surrounded by other princesses your own age? Camp Princess is the perfect place for any princess to find a summer of magical fun! And this year, for a princess named Alicia, Camp Princess will become something more—a place of mystery and adventure. Her turret seems to be haunted, and the golden bird that she captured for the songbird contest refuses to sing a note! It's all utterly frustrating—until one shadowy night, when Alicia feels a ghostly presence in her room and begins to discover a destiny far more exciting than anything she could have imagined.

When rumors of wild unicorns come to Camp Princess, there's a frenzy of excitement as the royal maidens prepare for the Unicorn Round-Up. But Princess Gundersnap has more important things to worry about. Her war-inclined mother has taken her beloved pony, Menschmik, into battle, and Gundersnap fears for his life. Besides, Gundersnap is much too practical to believe in unicorns. Or is she? Both the magical tapestry in the tower and her favorite local witch, Berwynna, seem to be trying to tell Gundersnap something. Could the Unicorn Round-Up be more than just a bunch of royal hooey?
