C21 fiction - The Wolf Hall trilogy, Hillary Mantell; by some margin the best prose I’ve seen this century.
C20 fiction - Pale Fire, Nabokov, a book to return to;
Pop science - Thinking Fast and Slow, Daniel Kahneman, a book that radically changed the way I think
The Selfish Gene, Richard Dawkins, ditto
Philosophy - Tractatus LogicoPhilosophicus - Ludwig Wittgenstein - depths made clear.
