Ask HN: What are some must read books?

Life is too short to read crummy books. So after reading the review on Blade Runner 2049 which touched on PKD and Nabokov I have decided get Pale Fire. I am curious what you would recommend on top of that (I was also planning to get A Confederacy of Dunces). That said, take a penny leave a penny, if you haven’t read A Supposedly Fun Thing I’ll Never Do Again or Gibsons’ Neuromancer, try and make time. They’re exquisite!
