If this is the first book you buy from this author, you will not be disappointed. It well describes the causes of 5 types of morphology and broadly enough so that we can find our way. The book is rather short but easy to read, even enjoyable. Now if you've read his two most famous books: "Listen to your body" Volume 1 and Volume 2 you may be a little disappointed. She has already addressed this issue in Volume 2 and here she develops a bit more about the origins of our different morphologies. This book allows us to learn and we certainly helps to understand us. But the solution is always the same: acceptance of who we are. For me this book is a chapter of more substantial "listen to your body" and I do not think there was room for a book just above. The commercial side is very visible. By cons I recommend reading "Listen to your body."
