Query: The Best History Book Ever

I am an avid history buff and by far this is one of the best and most comprehensive books ever! Once I started to read it, I was unable to put it down.If you want to experience the truth about this Great Nation and how we have come to the place we are now,then it is a MUST read.Every home in America should have this book.
