I know Dungeons and Dragons ensnared a lot of introverts, over the years, and if you weren't interested in complexity, you'd be playing another MMO, so I infer that many here are readers. With this background in place, what are you reading?
I've started The Thirty Years War by C. V. Wedgwood because I was interested in a lot of things I was reading references to in The Federalist. My last one for fun was The Diamond Age by Neal Stephenson.
