Seventh-grader Joanna Giordano wants to play ice hockey, but the only game in town is the boys' middle school team. Everyone tries to talk her out of playing--from the principal and the coach to the class bully, and even her best friend, Ben. But Jo is as determined as she is talented, and even a grandfather with Alzheimer's and a father who needs anger-management classes can't stop her from getting in the game.
