Fairy school dropout

"Elly doesn't just dislike being a fairy, she hates it! But now her grandmother is insisting that Elly take a trip to Rainbowville, the capital of Fairydom, to attend the Rainbow Academy for Fairies - boarding school! She has no choice but to find the end of the rainbow and get to Fairydom. But will this fairy school dropout finally become a proper fairy there?"--The publisher.
