First, with all the fearmongering about pandemics in the last couple of years, it is nice to read about the most deadly epidemic the world has ever known. It's not real comforting, but it is better than the fear Fox News was pandering at Rita/Katrina and the bird flu. It's a great book, one that should have been written, though it could have used a better editor. The book does jump around and there is a lot that probably could have been cut, but it is a great book dealing with a complex subject.
