An attachment theory frame meets the road map for therapy!
Format: Hardcover
Dr. Sue Johnson's scholarly synthesis of attachment theory and research, alongside her own clinical reflections/examples, culminates in a truly excellent resource! Dr. Johnson describes the value and utility of attachment theory so eloquently-- the wisdom contained within this text resonates deeply with the human experience and what we know to be true about the inherent and powerful longing for connection. She offers a helpful road map for therapy that is relevant, necessary, and essential for healing and change in therapy!

Wonderful read
Format: Hardcover
This is a super read for anyone interested in understanding more about relationships. It is not a popular press magazine or cookbook. Be aware it is written in a very dense (though fluid) academic style which requires your attention: compound sentences cleaned of articles and misunderstanding. The content is wonderfully organized and flawlessly edited. As a nonprofessional, I enjoyed the book immensely, finding insights into past relationships and myself on almost every page -- along with hope for doing better by my partner in the future.

Five stars
Format: Hardcover
The book was packaged well and arrived in perfect condition. It also arrived early which was great. I recommend this book seller. I read Susan M. Johnson’s other book on EFT, “Hold Me Tight” and found it extremely helpful with my therapy clients. I’m excited to dive into this book too!

This would have been great if an editor worked on it first
Format: Hardcover
As much as I admire Dr. Johnson and her work, the writing is not good in this book. The ideas are very useful but the reader must slog through complex, turgid sentences and multiple grammatical errors to get the points. I wish more writers had good editing and didn’t submit such poor writing for publication. Dr. Johnson is not alone in this criticism. I think many writers have been trained to write circuitous sentences and that results in the reader working unnecessarily hard to grasp the meaning of the ideas.
That said, I am very impressed by her use of research that supports her writing and the ideas she presents. I hope that future publications are more carefully edited before they are published, with the reader in mind. And if you wonder if I am uneducated, rest assured that I have a doctorate in clinical psychology and 20 years post license experience.

Great!!!
Format: Paperback
This book I feel really gives a great understanding of key topics and points that would potentially be on the exam. Although vague for some folks, potentially, they would be things to know and keep in mind when considering to cost of such an exam.
