Thistle Greenbud is not a bad fairy. She simply doesn't like rules, and it's just her luck that her homework is to create a new rule for the fairy handbook. But first, she has more important things to do. Like figure out how to get back at Dusty and Moss for playing tricks on her. Before she can carry out her plan, though, disaster strikes and she finds herself working alongside the very fairies she wanted revenge on. Can they work together and trust each other, or will things go from bad to worse?
