I've read several good fictional pieces this year and lots of wonderful to read once types but if I had to pick the one that will stay with me and that I'll probably go back to it would be Born To Run (non-fiction) by Christopher McDougal. He weaves a wonderful story from real life while throwing in some lots of things to think about from other cultures to evolution and biology. If you have a runner on your list I would definately suggest this one. Even if you don't run this is a good one.
