Here’s a brief quote from the review, be sure to read the entire review here
I love how The Princess and the Ruby an Autism Fairy Tale did not mention the word autism. I like that I was able to read this book as a fairy tale. Children who know about the diagnosis of Autism will understand and relate. The child who is not familiar can see that princesses some in all different forms.
