Shea Stonebrook is a typical 10-year-old girl from rural Pennsylvania. The problem is, she's a troublemaker. From not listening to her parents, acting badly in school, and everything in between, Shea is giving everyone a reason to give up on her. That is until one fateful day when an imaginative visitor decides to shape her point of view and offer her access to a place she never knew existed. In order for success, she will first have to accept responsibility for her actions, and only then will she be granted access to each new magical ladder within a mysterious world of enchantment, understanding, and life lessons known as The Great Green Tree.
