The Leftovers, by Tom Perrotta

Wonderful literary take on a post-rapture world. Intertwined characters within a small community have varied responses to the Sudden Departure, from joining a cult of silent Watchers to dropping out of college to follow an evangelist to tryoing to just enjoy the rest of their days. Beautifully written, and interesting for a serious writer to take on a topic more regularly approached in thrillers and in religious schlock.
