What Non-Baseball Books Are You Reading?

What non-baseball books have you recently read, or are currently reading?

I am currently reading The Kaiser and his Times by Michael Balfour. The book I read before that was Napoleon's Wars by Charles Eisdale, and the book i read before that was Roads of Excess, Palaces of Wisdom by Jeffery Kripal.  After I finish Kaiser, I will move on to Kali's Child by Kripal.

I am interested in what kinds of non-baseball topics interest the community, and this seems like a good way to find out.
