Tales of the frog princess

Although a princess, Millie cannot keep herself from turning unexpectedly into a dragon, so she ventures off to the Frozen North to find the Blue Witch, who she hopes will help her learn to control her dragon magic.

Thirteen-year-old Grassina vies with her older sister, Chartreuse, to see who will inherit the family's talent for magic and become the Green Witch, while each ponders which prince will be at her side during her "happily ever after.".
