PDA – Pathological Demand Avoidance
Ethan Knight — Teen Author
Ethan is my younger brother, and for years, people asked me about PDA in comments, messages, and emails — and every time, I found myself going back to Ethan with more and more questions.
Eventually, after a lot of nagging on my part, he agreed to write a book that explained PDA from his own lived experience when he was 18 years old.
But his journey hasn’t been easy. He struggled with learning and speech difficulties in early childhood and didn’t learn to read until he was ten. His determination, resilience, and unique way of understanding the world have shaped him into a writer who speaks directly and compassionately to readers who need clarity.
His debut book became an Amazon UK #1 Bestseller in Children’s Autism Spectrum and Educational Strategies & Policies, and reached #1 in Australia for Biographies of People with Disabilities.
But more importantly, it has helped families, teachers, and autistic young people understand PDA in a way that feels real and relatable.
