The Curious Incident of the Dog in the Night-Time.
I think some high school students might really dig it.
A really good book with a main character who had autism. One of the best books I've read in a long time. A little bit Catcher in the Rye, a little bit detective story, a little bit About a Boy. There are some really cool math problems in the novel and it makes you see the world from the eyes of someone with autism.
