Query: Avoid this best seller

I selected this book based on being a best seller, and personal interest in anthropology and history. Unfortunately, the book has little focus. It is hard to tell whether this is an anthropology survey, critique current anthropology research, or the authors personal travels. The reading is very slow and tedious. For me the book went too far when when drawing connections between a current day tortilla shop with pre-columbian peoples. I had to call it quits after 200 pages into the book. The reading is agonizingly slow, and includes assumptions with little or no supporting evidence. Based on this book I no longer rely on best seller lists.
