Any books that focuses on the relationship between brothers?

I'm looking for books with complicated brother relationships. I believe sibling relationships are one of the most complex, beautiful relationships out there and I want to read more of it. Everytime I come across books with brother relationships, I feel they lack depth and is almost always stereotypically depicted with a jock older brother who likes to pick on his nerdy younger brother. I don't mind this dynamic (probably not as uncommon as I'd like to think) but I want the relationship to be explored with more depth then that. Thank you in advance! 🙂
