Tennis Trouble

Alexis is only 13, but she made the varsity tennis team.  She's thrilled, but not everyone is happy for her--two of the older girls think Alexis ruined the season for their friend, who didn't make the team.  The older girls are out to make Alexis's season terrible.  Can she keep up her self-confidence and step up to the net, or will she let the girls get to her and lose everything?
