Book Recs for my boyfriend

Hi, my boyfriends birthday is coming up and I’m seeking advice for what books to get him, as someone who has really only read wattpad. He’s in to classic books from my understanding. He has read books like Donte’s Inferno, Pride and Prejudice, and almost all of the dune books (which I don’t think is a classic but it’s what I can remember rn) ect. He likes a lot of different periods of books from my understanding. If anyone has an book recommendations please let me know!!!
