Thanks, Hayley!
I'm really enjoying it. It took me a long while to get a handle on the plot (there are a lot of characters who are all intertwined in the same story) but, once I did, I really started enjoying it. I happily spent about 4 hours reading it yesterday.
I think "Jane Eyre", "Tess of the d'Ubervilles" and "The Great Gatsby" are all up there. I could re-read those three forever.
