Wuthering Heights by Emily Brontë
I have never read Wuthering Heights before, or seen any of the movie adaptations. I was vaguely expecting some sort of romance novel. This is definately not a romance novel. It's a tale of revenge, tragedy, and human psychology. Very few of the characters are likeable, but I don't think you have to like the characters to understand something of what Emily Brontë was trying to convey.
