Haddon, Mark. The Curious Incident of the Dog in the Night-Time.
This is an adult book appropriate for YAs.
This story is told from the perspective of a boy that is autistic. Chris lives alone with his father. One day he goes to a neighbor's house and finds her dog dead in the backyard, with a pitchfork through the body. Just as he picks up Wellington, the owner comes out and freaks out, assuming he has killed the dog. The police are called but nothing happens with it.
Chris, who is austic but also very gifted in mathematics, sets out to solve the murder mystery by talking to the neighbors. This is difficult for his since he doesn't like strangers, and he has limited social skills. Eventually, through his detecting, he discovers that his mother is alive, even though his father had told him she was dead. Years before she left them to go away wtih the huband of the woman that owned Wellington. Chris sets off on a trip to find his mother in London.
The story here is interesting and witty, seeing the story from the perspective of a teen with autism. It is not only entertaining but also shows what goes on in the mind of an autistic person. I recommend this to anyone that enjoys off-beat stories or is interested in autism.
