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 can barely name anyone in his class, and has trouble with the simplest things - recognizing people, pretending, and knowing when people are happy or sad. And yet he was only one of seven fourth graders in the United States to ace the National Math Olympiad. In fifth grade he finished second in a national math talent search. That boy is autistic, loving, brilliant and resilient. In this book, his father writes about the joys, fears, frustration, exhilaration, and exhaustion involved in raising his son. And, oh, yes, math. Lots about math.
