I was not impressed with this book. The glowing reviews are a mystery to me. Miller seemed to begin one train of thought jump to another and back again. The lack of organization was overwhelming. The dry, unexpressive writing was disappointing. As a text this is muddled, as "engrosing non-fiction" utterly lacking. Furthermore, this book was extremely long. The length is not necessarily a negative in itself, but it is when it seems that nothing of substance is being said. The length of this book can be attributed to the constant reiteration and the poor organization. Pure facts are as difficult to weed out as it is to understand the structure. Very disappointing.
