Great book!
Format: Hardcover
I loved the book. It’s a quick read as the novel is written beautifully through poetry. The main character is easy to love and root for. As a teacher who is always advocating for neurodivergent kids, I am often helping parents see the strengths and needs for their child. I love that a book exists where kids can go “That’s me!” and learn to love who they were created to be and find tools that help make the world easier to cope with. The author even gives suggestions and resources in the back of the book. This novel is timely as we are starting to have a greater understanding of the spectrum of Autism. Grandparents and parents are beginning to understand themselves through the diagnosis of their kids/grandkids or even nieces/nephews. Knowing yourself is a powerful thing as Selah (the main character) teaches us.

the BEST BOOK EVER to learn what autism feels like
Format: Hardcover
I have read just about every book ever written (in English) related to autism -- well over 700 of them. This is the best book that communicates what autism feels like, and our life experiences. I'm decades older than the audience the book is intended for; but EVERYONE should read this book to understand we who are different. It also points out several well-known facts: autism has some heredity trails, having just one trusted adult who treats the different child like they are valuable is key to that child being able to cope with the world around them. What surprised me was when an educator with over 25 years of experience in special ed, just did not think the book was that good. That convinced me of the book's unique value: it truly puts the reader in the body and mind of the different child. Some educators cannot do that. The story focuses upon a female -- so not sure how applicable it is to a male different child. I hope some others would test that out. The BEST BOOK EVER to understand what autism feels like. I know as I have been on the autism spectrum since before there was an autism spectrum.

Fantastic read
Format: Hardcover
Read as part of upper elementary book club with 4th and 5th graders. Told entirely in prose from the point of view of a 7th grade girl struggling with changing social dynamics and self-identity, we see Selah learn to advocate for herself amidst family and school challenges. This book made me laugh and cry, but more than anything, it made me cheer Selah on as she discovers what autism means for her.
