Books for a high school (almost) graduate

I just had my last day of high school today. Since I have to pass national exams in order to graduate, I’m not done yet, but in an in between where I know it’s the end.

I was wondering if anyone had any recommendations of books about the end of high school, like the bittersweet feeling of it, or just books that are good to read when becoming an adult.

Thanks to all who will read this post !
