Best book in this list?

Though I haven't read it, I've heard a lot of good things about The Great Gatsby, even by people who had to read it in an English class, which usually ruins a book. I read To Kill A Mockingbird this year and it was pretty good. Animal Farm was really good and if you're really interested in the history of the Russian Revolution and know a lot about it, it'd prove to be a really good read. It's very cleverly written so I'd definitely read it, and learning a little bit about the Russian Revolution beforehand would make it better. I haven't read either The Sun Also Rises or A Farewell To Arms by Ernest Hemingway, but he's a really good author cuz I have read The Old Man and The Sea. I'm sure these books won't disappoint!!
