Books by authors (or featuring characters) who are autistic?

I would like to read realistic portrayals of autism in fiction. Preferably from the autistic character’s POV.

I read The Curious Incident of the Dog in the Night-Time by Mark Haddon several years ago. I enjoyed the book and the way the protagonist was written. I‘ve seen criticism that Haddon’s portrayal is wildly inaccurate and not representative of what autistic people experience. Haddon’s response was that it’s “…not a book about Asperger’s. It’s a novel whose central character describes himself as ‘a mathematician with some behavioural difficulties’. Indeed he never uses the words ‘asperger’s’ or ‘autism.’” Haddon admits he has no experience with autism and did no research for his novel.

I would like to read authors who *are* actually autistic or at least experienced with those who are. Any recommendations for such authors/books?
