Which Book to Pick?

Well, so far I'm thinking about Great Expectations, The Last of the Mohicans, and/or The Lost World; Great Expectations largely because I've had it reccommended to me before, and Mohicans because it just seems kind of interesting. Both of those books have the drawback of being Realistic Fiction, however. The Lost World is a nice fantasy about dinosaurs, though, so it might be a bit better in my opinion.
