Abby the Bad Sport

Abby has joined a Special Olympics Unified Sports soccer team! Playing soccer every day with a new group of friends is awesome. But Abby expected to be the star on this team. And she's not. Erin is just as good as Abby. Maybe even better.
Abby doesn't know how to be number two. So she hogs the ball. And when Erin gets the ball, she doesn't pass it to Abby. Abby and Erin are in big trouble with the team. How did playing soccer turn into such a big mess?
