This book has some valuable information. Kimberly writes in a wholesome, caring manner which is very comforting to read, especially when it's regarding such difficult topics (e.g., trauma). There's some exercises to try, although the only one I liked was imagining yourself in a previous shitty experience, and saying aloud what you needed to say. The appendix is useful, e.g., the list of emotions, but there's not even much incorporation of it into the book itself.
However, for most of the book, I was waiting for more solid information, and it never came. A lot of this book seemed to be fluff and filler, and the actual content that was helpful only lasted a few pages every chapter. For example, there's only a few paragraphs about the medical trauma that women go through, especially to give birth. I would've preferred at least a few pages if not a full chapter on this topic. The reason I bought this book was to learn to read my own body/ understand when my body is saying yes or no, and this was barely a few paragraphs long.
A huge red flag for me is the lack of citations. There are no references. When she mentions something that appears to be a fact there's no way for the reader to know if the information is backed by evidence or it's an anecdotal observation. She discusses some common concepts in science like the fight or flight response, but I want to know the scientific support behind the novel concepts like fawning or freezing, for example. Not that she has to even discuss the evidence, but just show me that you have support for these claims. I think some scientific concepts are also oversimplified and could be better explained.
All-in-all, I haven't read many other books about trauma. Unfortunately, I learned so much less than I wanted to. There are probably other books that address trauma in clearer, scientific manners (E.g., the body keeps the score), but this book is a good first step if you're easily triggered, as it doesn't talk about specifics. I would give it 2.5 stars.
