Jack isn't exactly the most perfect member of the magical world. He might even have broken one or two rules . . . like taking his wand to school, and letting his best friend, Charlie, know that he's a fairy. Oh, and he did accidentally magic Charlie through an interdimensional portal to a sinister island prison for magical lawbreakers. Now he has to let his Mum and Uncle Dave know what he's done, and they have to rescue Charlie! Things take an unexpected turn when they arrive on Lonely Island. The bad fairies don't seem so bad at all-in fact, Jack thinks they are pretty cool. But one treacherous prison break later, Jack and Charlie realize they have been tricked. Can they work together to save the magical world, and will Charlie ever be accepted as an honorary fairy?
