What’s your favorite book that nobody else has heard of? You know, not Little Women or Huckleberry Finn, not the latest best-seller . . . whether they’ve read them or not, everybody “knows” those books. I’m talking about the best book that, when you tell people that you love it, they go, “Huh? Never heard of it?”
Well, most people have heard of Camus though not everyone has heard of The Plague, but I don't know that it's terribly obscure. Everyone knows LOTR. A lot of people know the Master & Commander series when I remind them about the movie.
So I guess that leaves a couple, though again, they're not super obscure. I really enjoyed Pilgrim by Timothy Findley and the Kristin Lavransdatter series by Sigrid Undset. I understand there's a "better" translation of the latter out, so I'll need to check those out. For me, Norway + middle ages, and Jung + history and immortality = fiction gold :)
