I've read seven Shakespeare plays in as many weeks, and I have to recommend two of them. "Titus Andronicus" and "Much Ado About Nothing" were my favorites. While not exactly beach books, they are fantastic reads you can get through in about two hours. I have the Pelican paperback versions. These are easier to carry around than a honkin' volume.
I liked "Titus" a lot because it was the easiest to read. I understood it right away, which was not always the case with the other plays. I think the setting - ancient Rome - had a lot to do with my comfort level. I dig that era.
"Much Ado" was great because it was easily understood, and so I didn't have to work at reading it. One of the lovers was frustrating to read about because he was such a gullible ninny. Anyway. Check it out.
