Most heartwretching queer books you’ve ever read?

I love reading sad books and books with queer rep/mc's so what are some of the saddest, heartbreaking, ground shattering queer books you've ever read?
Don't hold back, I want the tears and contemplation of my whole existence.

I know A Little Life is a popular recommendation for what I'm looking for but honestly, 800 pages is a bit much for me. I plan on reading it eventually, but I would like to get other book recs.
