Having read several Myers-Briggs related books, I'd have to say that this one was by far the most deep and insightful look into type. While the others give a good surface understanding of Myers-Briggs, this one delves deeper and explores the more subtle and intricate points of each type without losing track of the general overview. This book views type primarily from a Jungian perspective and eight of the chapters explore the eight Jungian types into detail using analogies, real life examples, and humorous cartoons to illustrate, making the more complicated aspects of type theory more accessible to the average type enthusiast. There is even a type test at the beginning which may give you a good indication of what Jungian type you are likely to be. This book is a must have for any type enthusiast but since it explores the deeper aspects of type, those who already understand the basics of type and want a more advanced understanding will probably get the most out of it.
