The Devil and Miss Prym: A Novel of Temptation by Paulo Coelho
This little novel is a quick read, but unfortunately, I didn't like it much. It's possible that I objected most to the parable-like style of it. I had the same feeling of impatience while reading Ishmael by Daniel Quinn: interesting ideas, but just get to the point already!
On the other hand, we had a very interesting discussion about it at one of the book clubs I go to.
