Hey, a resurrected thread.
I much enjoyed reading Persian Letters (Lettres persanes in the original French) by Montesquieu. It was written in the 1700s. The novel is about a couple of Persians who travel to France and write back home about what they see and do. Their correspondents tell them about all that happens in Persia during their absence.
The novel is very entertaining and thought provoking in its social commentary. As an old work, it's also in the public domain!
