I tried to be generous and give this book 3 stars, but I truly could not.
For most of the book, it felt like a 2.5-3 star book. There was nothing in it that I could not find in other books or that felt especially poignant to me, but I figured her frequent analogies could at least be helpful when talking with other people. It feels very introductory - but that's okay, because there's nothing wrong with a solid introduction! It was fine - nothing special, but fine.
And then about 80% the main text (not counting the resources at the back), the author used a racial slur three times on one page. It's very possible that she was unaware, so I tried to push forward. Then only two pages later, she dove into a multi-page analogy where she explains how she frequently uses Helen Keller's experiences to those of finding a way to conceptualize your trauma. The language and culture loss that many Deaf - and especially DeafBlind - people experience is not comparable to adults with a language foundation understanding their own experiences. Deaf, blind, and disabled people are often used as inspirational touchstones and examples for physical and mental health, and it's not appropriate. And quite frankly, it's just as inaccurate as it is offensive.
I skimmed the last 20% of the book, dipping in and out as things caught my interest, because I knew that if I set my book down after that chapter, I would not finish it. Overall, it was fine, basic and largely spent on analogies, but some people benefit from that content. For me, it was 2 stars and left a bad taste in my mouth.
