Books that would make someone cry (crowdsourcing ideas for a "Read it and Weep" library display)

I have a cute display idea ("Read it and Weep") but need some ideas for what books to put on it. I know a lot of people were emotional for On Earth We're Briefly Gorgeous and A Little Life, but I'm sort of lost on what else to seek out. What books actually made you shed a tear?

Edit: Thank you everyone for the suggestions! I don’t typically cry during books, so it’s been both helpful and enlightening; I’ll give some of these a shot and see if they break me, lol.
