The Secrets of My Spectrum
#1 UK Best Seller by Callum Knight
The Secrets of My Spectrum is a powerful and personal insight into autism—told from the inside out.
At 16 years old, Callum Knight set out to write the book he wished existed. After reading countless books and watching TV shows about autism—all written by adults looking in from the outside—he realised something important was missing: what it actually feels like to be autistic. So, he decided to explain it himself.
In this honest, often funny, and deeply moving account, Callum shares his experiences growing up on the spectrum—from being a non-speaker to finding ways to fit in, while still facing daily struggles few people see.
This isn’t a clinical explanation or a parent’s observation. It’s autism as lived by a child. Callum’s voice offers something rare: a firsthand perspective that helps readers truly understand the inner world of an autistic mind.
With space at the end of each chapter for reflection and notes, the book is also a practical tool for parents, teachers, and professionals.
Whether you're autistic, know someone who is, or simply want to understand more, The Secrets of My Spectrum breaks down stereotypes and reveals the strength in neurodiversity—with heart, clarity, and courage.
