Strong preference for French literature

I have noticed that I have a strong preference for French literature and I have never read anything French that I didn't like. I have adored Hugo, Zola, Proust, Flaubert, Balzaque, etc. I am currently reading an Arsen Lupen book by Maurice Leblanc and I also love it (it's a bit "younger" than the books from the other authors but not much).

I've read books from other countries too, and some I liked, some I didn't. It seems that only with French literature I liked everything.

To be honest, I have never been in France, I don't speak French... I don't have any particular desire to visit France (at least not more than other places).

I don't know why I have this preference. I think it could be narration but I don't think that narration is nationality-specific lol.

Up for a discussion -- do you also find literature from certain countries more appealing to you? Do you know why or is it just a coincidence?
