Stearns: Request

I am supposed to begin a book discussion group here in Slovakia. I haven’t the least clue of what book to read, and I was wondering if anyone had any thoughts on this. Criteria: Must be 1) a novel 2) of interest to a group of young Catholics, 3) not too long or too complicated, 4) by an English or American author, 5) with maybe some name recognition. One of my ideas is The End of the Affair by Graham Greene. Please comment if you have any ideas! Please!
