Nonfiction by Naoki Higashida.
This is basically a series of questions and answers written by an adolescent autistic boy in Japan. He is non-verbal, so it was written with a special alphabet grid, and then translated from the Japanese.
That synopsis sounds terrible, but it was actually very interesting. It's cool to see what is actually in this kid's mind, what he is finally able to say after being trapped in silence.
It's a reminder to all of us who are interacting with autistic kids, or other differently-abled people. Someone is IN THERE, whether the person is able to communicate with you or not.
