McKenna has always excelled at school and in gymnastics, but now that she's entering fourth grade, school suddenly feels hard to her. When McKenna's teacher suggests she get a reading tutor, she's horrified - until she gets to know her tutor, Josie, who is super-confident and who also happens to be in a wheelchair. Josie helps McKenna realize that what might seem like a giant roadblock is really just a series of small obstacles that can be overcome one by one, day by day. McKenna's confidence starts to blossom, but then something happens at the gym that sidelines her completely. Will she recover in time to join the competitive team in the spring?
