I missed out on a lot of classic literature, which I'm trying to correct. So I've just read The Great Gatsby for the first time, and then To Kill a Mockingbird for the first time that I actually remember and understand it. And I was thinking of moving on to the Diary of Anne Frank, but now I'm compelled to ask: are there any great books everyone has to read that aren't about how much humanity sucks? Is that, like, a prerequisite for great literature?
