I don't have very many books that I haven't liked. I think this is because I don't finish books that I am not enjoying or learning from. I figure there are too many books out there to waste my time on something that isn't worthwhile. So I toss the bad ones to the side and forget about them.
I can really only think of only one book that has disappointed me. It is Krakatoa: The Day the World Exploded by Simon Winchester. I was so excited to read this book. I love to read about volcanoes. Every time we move, I have another library of books about volcanoes and earthquakes to read through. So when I heard about Krakatoa a few months after the paperback edition came out, I was able to get it from the library and I started it immediately. But I was sorely disappointed. The book was not in the least interesting to me. I think it can only be because of the author, since the topics of the book are subjects that I love. I tried The Map That Changed the World a few weeks later, and felt the same way.
I decided to give up on Simon Winchester, but I know that many people very much enjoy his books. Is there another of his books that I should try that I might enjoy more? I've thought about his book on the Oxford English Dictionary, but I haven't been brave enough to try it. That is another topic that I find very interesting.
