I personally enjoyed (and was certainly impacted by) many of the books that I was forced to read during high school. The most memorable ones for me all fell into the "modern classics" category - To Kill a Mockingbird, Animal Farm, 1984, A Clockwork Orange, Lord of the Flies, Brave New World, The Diary of Anne Frank, and so on.
Don't sugarcoat 1984 quite so much. It is an important read, but it's also good to tell a reader that "the interesting bits" happen (very roughly) 2/3rds of the way in to the book.
At least it's not The Great Gatsby (blegh) 8 chapters of annoyance and one lonely chapter of actual non-world building.
