The Warrior Heir by Cinda Williams Chima
"Before he knew about the Roses, sixteen-year-old Jack lived an unremarkable life in the small Ohio town of Trinity. Only the medicine he takes daily, and the thick scar above his heart set him apart from the other high-schoolers. Then, one day Jack skips his medicine. Suddenly he is stronger, fiercer, and more confident than ever before. And it feels great until he loses control of his own strength and nearly kills another player during soccer team tryouts. Soon, Jack learns the startling truth about himself: He is a Weirlind: part of a underground society of magical people who live among us. At the head of this magical society sit the feuding houses of the Red Rose, and the White Rose whose power is determined by playing The Game, a magical tournament where each house sponsors a warrior to fight to the death. The winning House rules the Weir. As if his bizarre magical heritage isn't enough, Jack finds out that he is not just another member of the Weirlind, he is one of the last warriors at a time when both houses are scouting for a player. Jack's performance on the soccer field has alerted the entire magical community to the fact that he's in Trinity. And until one of the Houses is declared Jack's official sponsor, they'll stop at nothing to get Jack to fight for them."
