I'm just finishing Duel: A True Story of Death and Honour.

It's about the final duel that took place in Scotland in the 1800's and also a broader history of dueling in general. I read it because I like history and because I picked it up off the bargain table at Chapters for dirt cheap. It's an excellent book though.

I'm about to start reading the most recent edition of A People's History of the United States by Howard Zinn.
