All I listen to in the car are audiobooks and have been doing it for about ten years, so I have listened to a lot of books. My taste for books to 'read' leans primarily to sci-fi, but for audiobooks I have had to widen the selection as most of my audiobooks come from the library and their selection of sci-fi is pretty limited. My tastes still generally run towards fiction, but occasionally I'll mix in a non-fiction book that catches my eye. At the moment, I'm listening to 'Paris, 1919' by Margaret MacMillan. This is a non-fiction work about the post-World War I peace conferences that decided the national boundaries for many countries in central Europe, the Balkans, and the middle East; the disposition of Germany's colonies; setup the League of Nations; and established the terms of the Versailles Peace Treaty. I'm about 1/3 of the way through it and so far it is still interesting. It is surprising how little has changed in the world of politics in the last 100 years!
