As a studient in french litterature, I have to read a lot of books at the same time.

For college: Crime and Punishment by Dostoevsky, young torless by Musil (and that's the two books who are interesting in my degree this year)

For myself: I reading again Nietzsche, because, well, it's pretty dope and you can have a great experience reading it while you listening to some ambiant black metal. Schoppenhauer is a good one too.
I read Camus too. The stranger is one of my favourite books, because it shows perfectly how useless you are in some moods
