Now a major motion picture from Universal Pictures starring Bruce Willis. Sixteen-year-old autistic savant Simon Lynch is a genius with numbers, capable of unraveling any mathematical problem placed before him. Distant and solitary, he lives in a private world that no one can understand or enter--until he solves the wrong puzzle. Now the brilliant, damaged boy has broken an unbreakable code, and rogue FBI Special Agent Art Jefferson is his only protection against a pathological government security apparatus and the world's most beautiful, deranged killer. For Simon knows secrets that no one must know--and for that he must die.
