Hey,
I went to look up the book you're reading and what comes up is Unmasking Autism by Devon Price PhD. Is that the same book you're reading?
I'm about halfway through, and it's not perfect, but I'd say it's a worthwhile read if you are (or think you might be) autistic, or have someone in your life who is.
Fair warning, as much as there's relief and validation in parts, there's probably also some pain waiting in others.
