At the beginning of the semester, my English 11 Honors teacher told us that we were going to be doing SSR (silent sustained reading) througout the semester. Since we were honors students, he wanted us to read what he calls "smart people books." I chose Wuthering Heights because I'd been interested in reading it for a while. (Mainly because it's talked about in Twilight, which might sound kind of stupid, but it's true.)
I really enjoyed the book. It's so weird because I hated a large portion of the characters, yet I also kind of liked them and enjoyed reading about them. It doesn't even make sense to me, but it's true. There's something about how the characters are written that makes you root for them even when they're doing horrible things (especially Heathcliff).
This definitely isn't the happiest book, so if you want something cheery to read, I wouldn't recommend Wuthering Heights. However, if you want to read a book that doesn't have an incredibly happy ending, you should read this book. (I wouldn't say it's a depressing ending either, but it's definitely not an ending that makes you feel all warm inside or anything. At least, not for me.)
I think this is a wonderful book, and I'd definitely recommend it.
