So I'm reading Wuthering Heights...?

And Cathy just died! I'm DEVASTATED! But not as much as Heathcliff and Edgar. Is it going to get any better? I can't believe she died!! I love the book, its fantastic but I'm just shocked! Also, is Cathy meant to be a likable character? Because I do like her, but she's a bit of a ***** and so is Heathcliff! Are they meant to be liked?
