A "mystery" about a dead dog, told from Christopher's perspective, a 15 year old boy with Asperger syndrome. 
 I don't know if there are other books told from the POV of an autistic person, but this is the first that I've read and I found it original. Christopher is a very pleasant narrator, and being in his head is not as disturbing as I thought it would be. It's pretty logical and systematic actually, here are a few of his thoughts: 
 - He doesn't like the colors yellow and brown, so he won't eat anything in those colors or trust people of those colors. 
 - He can't stand people touching him and if that happens he'll scream or hit them to get them to leave him alone. 
 - He doesn't like being in crowded places because he gets scared and confused (understandable) and he'll scream or throw a fit when he finds himself in such a situation. 
 I didn't feel sorry for him for having this condition, if there's anyone I felt sorry for it's the parents. We follow Christopher through a painful time of his life, but it's not really that painful because Christopher narrates it in his deadpan matter of fact way. It took the gravity out of the book and I guess it works in a way. 
 At the bottom of it though, this is a story about a family dealing with an autistic kid. It's an entertaining book and a fast paced one. But all I can give it is 3 stars because at the end my feelings were "I liked it". I wasn't blown away. I just liked it.
