Fiction by Eli Gottleib.
This story is told from the perspective of a severely autistic boy, who happens to be about fifty years old and has been institutionalized for most of his life.
It's an interestingly limited perspective to tell a story from, and I'd imagine it's difficult to write. I enjoyed the story and the characters.
Other books from the autistic perspective I've read include the excellent novel The Curious Incident of the Dog in the Night-time and the nonfiction book The Reason I Jump.
