Well, actually, it's mainly Pride & Prejudice that I enjoy reading over and over. It's the archaic English prose, which must be additionally parsed and translated, and which sounds so lovely. It's the I'm-still-laughing-at-this character interactions. It's the wonderful pacing and the thoroughly realistic-sounding plot. I love the intelligence, the humor, the comfortable dresses, the enigmatic Mr. Darcy (who you like more every time you read it, because you see some new nuance), and the fact that book is not a long tome. For a book of that era, it's quite lively and very concise. There's not a single wasted word or scene in the whole book, no polemicizing. You get all the good stuff about that era and none of the Dickens- or Hugo-style "I'm getting paid by the word so I'm going to keep filling pages with them" prose.

Love it love it love it!

And aside from the Bible, which is a different sort of book altogether, I can't really think of that many books that I want to read again someday. "Redeeming Love," Francine Rivers. "The Sparrow" and "Children of God", Mary Doria Russell. "Ender's Game", Orson Scott Card.

I recently re-read the Lioness Rampant series, by Tamora Pierce. I remember loving it when I was 13, but it didn't quite live up to expectations at 25. :)

Beside, with so many UNREAD books still in the world, and limited reading time, I'd really rather read something new! :)
