Reading on Vacation

Every summer, I take a summer vacation near a beach. Most times, it's Cape Cod, but this year I'm spending a week on Block Island. One of the things I love most about vacation is discovering new books by browsing the books that live in the cottage in which I'm staying. This year I found John Adams by David McCullough, and so am laying down on the porch with a frosty beer and reading about the American Revolution. It doesn't get much better than this.

What are your favorite summer/beach books? I have to say that normally I indulge my weakness for Tom Clancy-style novels when i'm near the beach, so this year is a bit of anomaly.
