I just finished "Cod" by Mark Kurlansky. It came highly recommended, and I had no idea fish could be so instrumental in world history. Seriously, Cod played a big role in the discovery of America and the Revolutionary War among other historical events.
I, too, am now reading "Founding Brothers" by Joseph J. Ellis, but I've just gotten into it.
I recently read "Round Ireland With a Fridge," and I laughed all the way through it. It reads like a geography/travel guide written byJerry Seinfeld (a funnier Irish version of Seinfeld).
"I fought because I understood and could not bear to understand, that it was my destiny -- unlike that of my father, whose fate it was to hear the roar of the crowd -- to sit in the stands with most men and acclaim others. It was my fate, my destiny, my end, to be a fan."
