Enrolling herself into Mortimer Potts Elementary School without her parents finding out won't be easy, but Bluebell Skinks has a plan. In just three short weeks, she will prove to the world that a wheelchair kid can cause just as much chaos as a regular kid, and have a blast doing it. With the help from her new friend, Frederick "French" Frye and advice from her sensible sister, Bonnie, Bluebell turns the school upside down by orchestrating an energetic student election, a frenzied disability day, and an extraordinary science presentation. Principal Grimble and Nurse Krutsky become caught up in the events with hilarious results, while Bluebell's uniquely talented classmates help her stay one step ahead of Hoops Russell, the school's star basketball player who believes Bluebell is faking her disability. After Hoops sets out on a mission to discredit her, what happens next will surprise everyone, especially Bluebell.
