Query: Terrible Book; worst book I have ever read!

If you need something to keep your door or window open and think you may never read it this is the book for you. I bought this book thinking that it is new and saw the all-star list of authors but I am so disappointed. DON'T WASTE MONEY!! PLEASE DO NOT BUY THIS BOOK! Buy Demay's Cytopathology instead. The authors should be sued for this crappy piece of work.
