Callum Knight

The Secrets of My Spectrum — Callum Knight

A first-person memoir

 

Callum wrote The Secrets of My Spectrum at just 16, sharing his own experiences of sensory overload, anxiety, education, friendships, communication and finding his own way. His experiences. His words. His perspective.


The Secrets of My Spectrum became an Amazon #1 bestseller and has since been read by families, educators and autistic readers around the world.


This is Callum's personal memoir and lived experience — not medical or clinical advice.

⭐⭐⭐⭐⭐

"Thank you, Callum. This book has been so important for my 13 year old son and I. It is the first book about autism he has wanted to engage with, and it has really helped us have open conversations. "

 — RW (Parent)


⭐⭐⭐⭐⭐

" I got this book after hearing about it on social media. I have been reading it every night with my 7-year-old.. He has found it very reassuring that other children have felt the same as him, and I find it invaluable to understand how he views the world. As he grows into a teenager, it will really help him. Great book. "  — Mrs T Flower  (Parent)


⭐⭐⭐⭐⭐

"It is an insightful resource that would greatly enhance the quality of support and understanding and foster greater inclusion. Thank you."
