I am reading this book as our March book club book.  I hate it.  It is the most boring book that I have ever read, next to the Source, by James Michner.  It is taking me a half hour to read one page.  It may be a Pulitzer Prize winner but it's awful.  Choose another book.  Don't get this one.  I love history but this book is not history.  It seems to be all over the place.  It goes from 11000 BC to 4000 BC to 1492 and from New Guinea to Australia to North America to South America with no connection.  I'll say it again, I HATE THIS BOOK.
