Between finishing late school projects and looking after her brothers and sister, Faith Patel barely has time to play soccer. And when she’s at practice, surrounded by girls who can afford to play in club leagues, she doesn’t even feel like part of the team. So when Coach Berg starts to give Faith extra attention, she feels . . . really special. It might be crazy, but suddenly Faith has a crush on her coach. Can she keep her head in the game? The situation gets worse after Faith’s frenemy Caitlyn decides that Faith’s getting special treatment. Will Caitlyn tell the rest of the team-and make Faith into a total outcast?
