[Alyssia]

That would have to be Wuthering Heights by Emily Brontë. I picked it up once when I was younger and couldn't get past the first chapter. I picked it up again recently and I couldn't put it down really. I just sucked me in.

If you like unrequited love then you should look into it, although it does take some getting used to.
Snippet about it from wikipedia

"The title of the novel comes from the Yorkshire manor on the moors of the story. The narrative centres on the all-encompassing, passionate, but ultimately doomed love between Catherine Earnshaw and Heathcliff, and how this unresolved passion eventually destroys them and the people around them."
