I agree with the Washington Post review. This book is very disorganized. It is filled with personal opinions that are not properly cited. The reference notes are not in the text and it is very difficult to determine the author's sources. He jumps around fro era to era and geographic location to location. I learned more about the pre-Columbian Americas in the museums in Mexico City and Lima than from this book. Furthermore a high percentage of the material is post 1492.

I am very surpised at the high praise given this book and have to believe most reviewers did not read it; rather took their reviews from publicity releases.
