Game Theory

Jamie is a 16-year-old math whiz. Summerlee, his older sister, is in the grip of a wild phase. Tensions at home run high. When Summerlee wins a 7.5-million-dollar lottery, she cuts all ties with her family. But money can cause trouble—big trouble. And when Jamie's younger sister Phoebe is kidnapped for a ransom, the family faces a crisis almost too painful to bear. Jamie thinks he can use game theory—the strategy of predicting an opponent's actions—to get Phoebe back. But can he outfox the kidnapper? Or is he putting his own and his sister's life at risk? An astute, page-turning novel from a superb storyteller.
