This book is really good. It’s straightforward, has a great layout, was clearly well-researched, and lifts up Autistic voices. Yenn Purkis has contributed so much great insight and knowledge regarding the intersection of autism and mental health, and this book is a credit to them.
It loses half a star for using person first language, and references to functioning labels (including lots of the use of Asperger’s). I’m guessing it’s more a symptom of when it was written (and possibly done to please the publishers), but some would find the language used frustrating and/or triggering.
I love what the book is doing though, and have learnt from it.
