Can y'all recommend me long stories that are actually worth reading?

To be honest, I drop most stories after a while if they're too long, not necessarily because they're particularly bad, but because they just get too boring for me and drag on too much for me to keep up with them.... Plus, I have the memory of someone with dementia, so after a while I tend to forget half the story, especially if it’s an ongoing series (and once I’ve finished a story, I usually forget it pretty quickly unless it left a lasting impression, so that I can read it again later as if it were the first time )

So please recommend something that has really stuck with you!...Any genre is welcome, thanks in advance!
