It has been many years since I read it, so my memory of the details is fuzzy. I don't remember it being a "page turner," but I remember enjoying it. I think what helped motivate me is the knowledge that it is considered by some to be the "Great American Novel." That made me curious to see why. Another fact that might help you is knowing that it is not just a "fish story." If you seek out commentaries about Moby Dick, you will see many theories about its deeper meanings and symbolism. On a different level, it also could be a lesson about obsession and the self destructiveness of seeking revenge.
