Anyone ever being shocked by the popularity a book from your country have received in foreign countries?

I’m from China and while I cannot think of a book from my country, I sure shocked quite some of my American friends with how much I love “gone with the wind”, as it can be controversial(so to speak).

Any examples you guys can talk about when a foreign friend of your surprised you with how much they love a book from your country that you either hate or never ever heard of?
