There has been an increasing amount of discussion and interest in what is now known as the Autism spectrum, which includes Asperger's syndrome. The Curious Incident of the Dog in the Night-Time is a piece of fiction written as if the author/narrator is a teenager with Autism. He is pretty far to one end of the spectrum where he has violent reactions to being touched and similar behaviours that are atypical in most of society. The other end of the spectrum has people who have been able to learn more about people's emotions and societal norms which enables them to emulate those behaviours and hence fit in.
I found this book to be very interesting. It was a good story first and foremost. There were some plot twists, a decent amount of character development, and generally the writing was clear. One has to take into account the way someone with Autism thinks in order to really appreciate the book. I found the view into this kid's mind to be enlightening. As his thought process is quite logcial and fact based, it was quite easy to read this book very quickly.
