I’d bring Ramon Saizarbitoria’s Martutene, Vargas Llosa’s The War of the End of the World, and Miau by Benito Pérez Galdós. I could spend years rereading them. Plus, they are long. I wish the question included a fourth book so I could add Theodore Dreiser’s An American Tragedy.
When people say “the Bible” in response to this kind of question, I feel like they are virtue signaling.
It’s worse when they say War and Peace. Are you really going to read that crap? How many times?
