I've been pretty avidly on the trail of enneagram information that I can relate to and apply. This is one of the best books I've come across. I especially appreciate how the different types are described in both work situations and love relationships with examples of one type with another (example: a 4 employee with a boss who's an 8). Because of my enthusiasm for the book, I did a quick read and then promptly lent my copy to someone else. I'm already wanting it back. This is a book that won't stay on the shelf year after year. It's much more the kind of book that is so packed with information that I'll read and re-read it, sections at a time, for years to come. I'd consider it a must read for anyone intrigued by the enneagram.
