I have no problem with the content of this book. The problem is with the book itself. I got my order in very fast from amazon, but immediately (and I mean within hours) the pages started falling out. I'm not one to complain about the quality of books, but this book is clearly poorly made. I have a classmate who bought the same paperback and I laughed because the first question he asked me was if my pages were falling out. Buyer Beware!
