Some people think this book is only for beginners. I disagree. It seems simple because McWilliams is a gifted writer and teacher, and has a knack to explain the most difficult concepts with everyday language that a 6 year old would understand. If you want an easy read with a lot of substance, read McWilliams. If you want a painful read with little substance, read Lacan (haha.) I am a beginner therapist, and this book has helped me immensely. The professor that recommended it has been practising for 35 years and *still* finds it useful. (Note: he is a renowned clinician and scholar... not just anybody)
Every sentence counts. There is no superfluous material here. You get your every penny's worth of information. The book is also a page-turner--since when is a textbook supposed to be this enjoyable??? And McWilliams, who is obviously comfortable in her own skin, does not show the dogmatism that is typical in other writers. She is open to admit the usefulness of other approaches to therapy, and this very openness makes this text a useful resource for anyone interested in psychotherapy, even if they are coming from a different approach (cognitive behavioral, humanistic...).
