At the bookstore and I need a good book to read!

Hi! I'm at the bookstore and I have no idea what book to read.

I'm looking for a modern type of mystery or like a dark depressing "coming of age" or something like that lol it's hard to explain. Something with a lot of character development. Where bad shit keeps happening and you feel bad for the main character or something. Nothing to do with fantasy or magic as I have read a lot of those in my day lol

I recently finished the book "then she was gone" and I really liked that book to give you a sort of idea.
