Guns, Germs and Steel: The Fates of Human Societies
Took me a year and a half to read this book. Not only because I'm a slow reader, though I am. But it was so long and there were so many other activities and books clamoring for my attention, that I got sidetracked several times. But it was worth coming back to. It's a fascinating study of how human societies succeed or not, in macro terms. It's very well written, but very long.
