Ethan is a 19-year-old author who brings a rare and heartfelt perspective to the topic of Pathological Demand Avoidance (PDA) in his debut book, written when he was just 18.

"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. It would also be great for explaining PDA to extended family and friends. Maybe even busy educators and health professionals could find time to squeeze it into their day.
