In a little over a week's time, I'll be spending at least four hours in a cyndrilical* tube, breathing recycled air and trying to avoid eye and thigh contact with total strangers seated uncomfortably close to me. And at least a hour in the airport beforehand.
I'm looking for something entertaining to read on a semi-cross-country flight, preferably something that wouldn't be sold in an airport gift shop/bookstore. If you've read something (such as a book) recently that you've enjoyed, feel free to leave the details in comments.
* I should have said "tubular."
Update (7/20): Thanks to everyone for your suggestions, and for making my choice so difficult.
