As far as textbooks/required reading go, this book is actually fantastic, and I learned a lot from it! I guarantee that I'll continue to reference it in the future.
I'd give it like 4.5 stars because I thought that the conversation surrounding autism missed the mark for me. At one point autism was referred to as "a tragic storm", and while I understand that from a neurotypical/allistic perspective the mechanics of autism might seem "sad," I think it's a mistake to assume that that reflects the lived experiences of people with autism. There were a few other points in the book where I was rubbed the wrong way about commentary on autism, but suffice to say that if one is willing to overlook the overgeneralizations about autism (including some "comclusions" that seem to really stretch the scope of the actual research), the rest of the contents of this book are phenomenal and very eye opening.
