Amethyst, princess of Gemworld
Shannon Hale
Sophie is a young witch whose mother and grandmother pressure her to attend the Royal Magic Academy, the best magic school in the realm, even though her magic is shaky at best. To train for her entrance exams, Sophie is sent to relatives she's never met. Frustrated, Sophie attempts magic on her own, but the spell goes wrong, and she accidentally entangles her magic with the magic of a young water dragon named Lir.
