A little nine-year-old boy looks down at the gymnasium floor. The room is filled with children who like and respect him, but he has no real friends. He can barely name anyone in his class, and has trouble with the simplest things - recognizing people, pretending, and knowing when people are happy or angry or sad. Much of his life has been filled with anxiety. He is out of step with the world, which to him is mostly a whirlwind that must be actively decoded and put into order. And yet he was only one of seven fourth graders in ... Read morethe United States to ace the National Math Olympiad. In fifth grade he finished second in a national math talent search.

That boy is autistic. He is also loving, brilliant and resilient. In this book, his father writes about the joys, fears, frustration, exhilaration, and exhaustion involved in raising his son. He writes about the impact on his family, the travails of navigating the educational system, and the lessons he has learned about life, what it means to connect with other people, and how one builds a life that suits oneself. And, oh, yes, math. Lots about math.
