The first major turn off of this book is the insistance that Native Americans crossed the land bridge to inhabit the lands known as the United States. After many, many decades, I find it appalling that authors continue to perpertrate this myth! With that in mind, I didn't care to read any further into the book as I really did not want to be confronted with more writings that perchance were historically inaccurate. The author's lack of attention to this type of Native American historical detail is a huge thumbs down.
