On his Facebook wall, SR colleague Jim Kershner writes: "I just finished my summer reading project: "Les Miserables," all 1,463 pages of it. Yes, it was well worth it. I was actually sorry for it to end. But next time I'll tackle something easier, like reading the encyclopedia backwards." I've also read "Les Miserables." It's probably the longest book I've ever read. How about you?

Question: Which book is the longest you ever read?
