What Readers Are Saying
⭐⭐⭐⭐⭐
A Masterclass in PDA/Autism
— Brian, Autism Support Community
⭐⭐⭐⭐⭐
Great insights about living with PDA and ways to help.
Loved this book, easy to read and so much I could relate to in terms of how I think our PDAer experiences life.
I highly recommend this and think it would be great for anyone trying to understand themselves or the PDA profile - the writing is clear and not too wordy, meaning it could be good for younger tweens and teens, and for siblings of PDAers.
— Steph Curtis - Author of PDA in the Family
⭐⭐⭐⭐⭐
I didn’t even know what PDA meant. As soon as I received my book through the letterbox, I read it from cover to cover; I never read. It was like being in my child's mind, as if he had sat and written it himself. Everything finally made so much more sense.
