Thus far on the trip I've read Bill Bryson's "Neither Here nor There" (gift from Dave, writings on travel in europe) and Dumas' "The Three Muskateers."

The former was quite funny, especially all the potshots about Germans, but was funnier for the first half and then dragged a bit. I'd still recommend it though. The latter was enjoyable, but sadly much too sexist to go on my "books I will read aloud to my children someday" list.
