Ask HN: I'm going on an internetless vacation today. Any book recommendations?

In about 6 hours I am heading south to an all inclusive resort for a week. There's no internet, and not much for TV, so we plan on doing a lot of reading on the beach. Does anyone have book suggestions? So far I'm taking down Deadhouse Gates by Steven Erickson, Walden by Thoreau, and a book on the Philosophy of Language to mess with my brain. Any kind of book will do, but bonus points for books that I can learn something from but aren't ridiculously difficult, are travel friendly, and I can probably find at a university library. Let me know some of your favourites. Thanks!
