I read through Adventures of Tom Sawyer/Huckleberry Finn at one point. They were fine, had to google a few archaisms. Not exactly thrillers, but even as a euro, I just felt the Americana, I guess. Charming as a period thing.

On the other hand, I read 1984 and was actually surprised at how engaging it was. Major bummer, obviously, but I expected it to be an effort. It held its own and kept me reading.
