People are writing a fair number of YA books with Aspie or autistic characters lately. I could make a list if anyone wants it. Right now on my TBR is Anything But Typical and Buster and the Amazing Daisy and I started Marcelo in the Real World a while ago but didn't feel like finishing it. (It's very good, but the narrative voice seemed like every other fictionalized aspie and I got bored with that. Wish someone would write a book about a funny, sweet Aspie like my son.)
I read a romance a while back called Chasing Stanley and the female lead seemed very Aspie-ish to me, although her official diagnosis was something like Social Anxiety Disorder.
Edited to add: I just picked up Anything But Typical and it looks like yet another first person narrative with no contractions. For crying out loud! My son is the classic "Little Professor," he's always using long words and complicated phraseology. But he uses contractions!
