This book does a great job of making vivid the 27 subtypes of the Enneagram, primarily by giving examples of characters in film or television who represent those types. Enough plot and description is given that even a person unfamiliar with the film gets the picture.
This is a much larger and more developed book than Rhodes' earlier one, The Positive Enneagram: A New Approach to the Nine Personality Types. The book falls into three sections. In the first part, Rhodes rambles through a range of Jungian and Integral authors along with her own thoughts to present the concept of Soul as opposed to body or spirit. I found this surprisingly enjoyable, if not systematic (but then, she's a four!) The second section reprises some of the history of the Enneagram and of her positive take on personality covered in her earlier book, although in a more mature way. While Gurdjieff students will be put off by some of her comments (she doesn't seem to grasp the Law of Three), her comparison of the Process Enneagram (I suspect from the Systematics work of J. G. Bennett) to the personality Enneagram is original and insightful, and made the personality types make sense to me as opposed to simply being a random collection of personalities strewn on a funny-looking diagram.
The third part, and by far the largest, is the before-mentioned description of the nine types and twenty-seven subtypes. She also attempts to associate archetypes (in the Jungian sense) with these subtypes.
Anyone interested in Enneagram work will find this book invaluable. No other book I have encountered comes near to presenting such telling descriptions of the types, let alone subtypes. Strongly recommended.
