That's all I can give away without spoiling the story. There are several adaptations available including a BBC miniseries on the novel and movie that is already available/will be available April 8th. I plan to see the movie and write a review as well.
Overall, I would say this is an excellent book worth reading. Yes, it is a classic and most people who see a classic run screaming, "AH CLASSIC! I AM NOT SMART ENOUGH TO READ THIS/ NOT STUCK UP!" One does not have to be smart or stuck up to read a classic. One just simply has to be willing to learn.
