The Outsiders was an amazing book, and I still quote it to this day. One of the most memorable books we read in school.
Never got to read Catcher in the Rye, unfortunately. But I think our curriculum made up for it--my school seemed to have some weird hard-on for speculative fiction and sci-fi, so a lot of our reading got to be short stories about robots gaining humanity and the like. Interesting stuff for tiny existential crises in preteen form to read.
