"You could spend years finding the patterns in first-person accounts of how autism manifests in various individuals – or you could read this book. As a late-diagnosed autistic woman, I wish it existed earlier. For other adult women seeking an autism evaluation, I would confidently recommend any clinician who reads this book and its companion guide. (That’s a big leap from my previous recommendation, which was to only see a clinician who has previously diagnosed another autistic woman!)" ― Annie Kotowicz, author of What I Mean When I Say I’m Autistic: Unpuzzling a Life on the Autism Spectrum

"This book presents a respectful, rich, and expansive description of what autism really looks like across individuals.

"Is This Autism? takes you on a personally guided tour into the hearts and souls of autistics. With the knowledge that Donna Henderson and Sarah Wayland have harvested from decades of personal and professional work, they convey the many twists and turns of the developmental journey of autistics. One phrase stuck with me in particular: 'A sense of belonging.' This desire to be validated for who we are – no matter how we show up in the world – lies at the deepest core of every human’s longing. Henderson and Wayland show us – with compassion and inclusivity – not only how to be informed about autistics, but how to be wise as well. With solid research, practical suggestions, and moving narratives from the experts who live the neurodivergent journey, we are invited to understand that only by knowing what is on the inside, can we – as professionals and family members – help on the outside. This book will become an essential guide for those of us committed to creating a world that adapts to and celebrates the unique experiences of autistics." ― Rick Silver, MD, psychiatrist, founder, and director, The THRIVE Center
