I started off with "Adventures of Huckleberry Finn".......but I think the Tom Sawyer one came first, because it seemed to reference past events that possibly transpired in a prequel, so I stopped reading that.
I started reading Romeo and Juliet then, since I enjoyed reading and acting that out in high school. I got too involved reading while I was reading it though..........I started reading it allowed on a bus, which embarrassed me a tad.
