This book's been praised by a bunch of literary people (e.g. winner of the Whitbread book of the year) for its evocation of an autistic boy. However, for the computer scientists and mathematicians among us, it's a bit 'yes, and? That was the guy sitting in the front row of the lecture theatre' (or, occasionally, 'that's me').
Maybe I'm being a bit harsh. It's quite a fun book. A bit different, but nother amazing.
