Two books I would highly recommend for lockdown reading and have cool European (Italian) type vibes are "Gomorrah" and "The Leopard" I read them both in my Italian film class and they were awesome books. They are also both pretty cool movies, Gomorrah was in Italian but in Neopolitan dialect that was so strong that it had to be subtitled in formal Italian for the rest of the Italians that couldn't understand the dialect.
Gomorrah is about two kids in the Naples suburbs who are trying to fit in with some gangs but can't really handle the life.
The Leopard is about times during the Italian revolution before the country was unified under what we know it as today.
That Paris book certainly sounds like it covers a lot of ground. I'm currently going through my old box of fiction novels before I work on other books. Currently reading Dean Koontz, "Odd Thomas."
We have so many other things to do these days with online stuff, streaming TV, gaming etc. But for me books are still right up there in the list of things to do for relaxation. I wonder if people will get back to it as they run out of things on Netflix. I'll have a look at those books you mention and thanks for commenting.
