Sounds like me when I downloaded Moby Dick on there... I haven't touched it yet. 
There was another one I tried to read a few years ago, The Life and Opinions of Tristam Shandy by Lawrence Stern (Which they made a movie of years ago). I found it very difficult to get into because the story's told in first-person, and the language used in the descriptions made it hard to understand, as it was antiquated enough to have lots of words no longer used. There's something about it being in first-person that makes it that much harder to read.
