I finished reading "Saturday" this weekend. It's a good read. It's the story of a neurologist in London who has a run-in with a street thug. This sets in motion a series of events that take the main character to the end of his resources to try to protect his family and way of life.
The really fascinating thing to me is that the author uses the events of this day to explore the arguments and possible conclusions about terrorism and our responses to it. It does it without being preachy, without forcing a conclusion on you, and it also shows the alteration in the western psyche as a result of 911. I enjoyed it quite a bit.
