Give me book recommendations

So I finished reading A little life (I am in SHAMBLES rn) and I'm back to my reading books era, so recommend me the BEST books (if it could be sad or dark or traumatic or just like a little life it would be great) you've ever read. Also I LOVE plot twists btw so recommend me stuff that will blow my mind (I'm not really into detective stories tho)
It can be online novels (stuff like orv as an example) or wtv it don't matter
