It's difficult to see the title/author in the reader, but I think this is it:

The Secret of the Book, by Erin Fry.

I've not had time to read much since Saturday, but now Socrates has come out of the book, and mysterious man came to Spencer's (main character.) door.

They do a good job of explaining some of the things which people who are autistic do, think, and feel.

For example, Gregor, Spencer's friend, taps his leg with his fingers. He does not accept physical contact well, he eats certain foods on certain days of the week, etc. And, if things change his routine, he gets upset. That can manifest in a meltdown.

It makes me wonder if the author has a family member who has a form of autism, and is using her book as a platform to familiarize people with it, possibly breeding more tolerance when the readers meet someone who is. Possibly in one of their classes, since it is a young persons book.

Whether intentional, or not, I think that it's a good thing for kids...and adults.
