The Comeback Challenge — Matt Christopher

Mark Conway is staying with his grandparents while his parents fight over whom he will live with after they divorce. He's become a valued member of the middle school's soccer team and has made friends with everyone on the squad -- everyone, that is, except the team's captain. But he's coping with both situations just fine. Or is he? When Mark explodes with anger on the field one day, no one is more surprised than he is. What is at the root of his anger, and will he be able to control it before it consumes him?
