Sad book recs

Hi! I’m looking for sad book recs that will rip out my soul. I like books with sad endings, major character death, doomed narratives/characters. Emphasis on sad endings cause I love books that dont have a happy ending!! Books that fit this vibe that I have read and loved are: if we were villains, the outsiders, blood over bright haven, Babel, the poppy war, dead poets society, sunrise on the reaping (alien stage, it is not a book but if anyone has watched it). Books I did not like that people said were gut wrenching were: a little life, if he had been with me (I like sad romance plots but not sad romance books, where it just focuses on the romance). I will read any genre (though I’m not a big fan of ww2 books) and would prefer standalones but if you have series I would still love the rec! Thank you and I hope this made sense and sorry if I rambled!
