I won't be putting any more recommendations on here right now but you can still put recommendations in the comments that people can read without looking at the video. Here are some autism-related books or books with autistic characters that I would recommend and a bit about them. After all the 5 books have been introduced, press space to learn a bit about them.
A big thank you to @the_awsome_chicken for the book recommendation of PAWS! Update log: -i'm adding PAWS.
