Since being featured briefly in Lost earlier this season (I believe it was in the episode entitled "Orientation" but I could be wrong), Flann O'Brien's novel The Third Policeman has been selling like crazy.

The book's US distributor and publisher reported that after the episode aired, over 15,000 copies were sold in about three weeks. That was the same amount that had been sold in the previous six years. It was revealed early on that the book was picked for a very specific reason, so readers have been scouring every word to hopefully find a clue about the hit ABC show.

Who knows what they'll find but the publisher warned that it may be tough since O'Brien's work tends to be very humorous, satirical, and surreal all at the same time. So if you bought it, good luck and do me a favor - when you find the clue or whatever it is, leave it in the comments for this post.
