In the interest of full disclosure, I should mention that Ann Ulanov is my thesis advisor, so, take that for what it's worth.
That being said, I gave the book 4 stars because while many of the ideas presented in the work are brilliant, the writing style itself can be heavy, circuitous, and tiring. This improves in the second, disappointingly brief, section of the work, titled, "Healing," but in the end attending a lecture by Dr. Ulanov is far more engaging than reading this book, which she penned with her husband.
