Which book have you underlined the most, filled with the most annotations;the one where every three pages you had to jot down a brilliant quote?

I’m generally not very original: The Little Prince, The Picture of Dorian Gray, Marcus Aurelius’ Meditations, Borges’ short stories… but recently I’ve discovered a less widely read author (even though she won a Nobel Prize),Olga Tokarczuk. I have to stop every two pages to reread and underline some sentence.
