Just two? I've narrowed it down to Melville, London, and Murasaki, and I can't decide which one to drop. I tried 'Confidence Man' a few years ago and had to set it aside because it was very strange and I couldn't focus at the time (it's more demanding than Moby-Dick, I'll say that much), but I still intend to get back to it someday. I'm planning on giving 'Genji' a second try sometime in the next month or so--tried reading it during a camping trip two years ago and gave up, but this time I decided to prepare by reading several ladies' court diaries of the period along with
The World of the Shining Prince. And I haven't tried London yet, but 'Iron Heel' has been on my must-read list for years, simply because it's a lesser-known dystopian novel by Jack London.
So yeah, read those three.
