The Silver City Ballet (Paperback, UK ed.)

When Megan winds up her antique music box for the first time, she hears a tiny voice calling over the sound of the music - it is the Fairy Queen of the Land of Eight Kingdoms, a magical place far away! She has been imprisoned in the box by the evil enchanter Sorcero, and needs Megan's help. Megan will need to venture into the magical land to break the spell imprisoning the Fairy Queen - all the while keeping her identity a secret. Megan's first adventure in the magical land takes her to Eliza Swann's Ballet Academy in Silver City, where a terrifying giant has turned up for a dancing lesson!
