After being diagnosed autistic at 13, Callum discovered that many books explained autism—but very few explained what it actually feels like to live with it every day.
At just 16 years old, he decided to change that.
Instead of medical definitions and complicated terminology, Callum shares his own experiences with honesty, warmth and clarity, helping readers see the world through autistic eyes.
Discover Callum's honest experiences of:
• Sensory overload and shutdowns
• Stimming and self-regulation
• Anxiety and navigating social situations
• Special interests and passions
• Education and growing up autistic
• Friendships, communication and empathy
• What helped—and what didn't
• Reflection pages after every chapter for your own notes and thoughts
This book is ideal if you are:
✓ The parent or carer of an autistic child
✓ A teacher, teaching assistant or SEN professional
✓ Newly diagnosed and looking to understand yourself better
✓ Supporting an autistic teenager
✓ Looking for an autism book written by an autistic author
✓ Searching for an easy-to-read guide without medical jargon

"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, who is autistic, specifically with Pathological Demand Avoidance. 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."
