"Braniac" by Ken Jennings is a behind-the-scenes memoir by America's quiz-show king. Back in 2003, Jennings auditioned for "Jeopardy!" Two years, 75 games, 2,642 correct answers, and over $2.5 million in winnings later, he emerged as trivia's undisputed king. "Braniac" traces his rise from anonymous computer programmer to nerd folk icon. Along the way it explores his newly conquered kingdom: the world of trivia itself.
