Back in his old basketball league, before the car accident, thirteen-year-old Carlos Cooper owned the court, sprinting and jumping and lighting up the scoreboard as his opponents (and teammates) watched in amazement. But now, Carlos feels completely out of his league on his new wheelchair basketball team, the Rollin' Rats. After all, how can he make a layup when he's still struggling to learn how to dribble?

But when the city's crooked mayor threatens to tear down the Rollin' Rats' gym, Carlos realizes that he can't stay on the sidelines forever. Because without a gym, the team can't practice, and if they can't practice, they can kiss their state tournament dreams goodbye. If Carlos is going to learn what it truly means to be part of a team and help his new friends save their season, he'll have to either go all-in . . . or get out.
