I love novels that have long, winding narratives that require you to take notes and highlight a bunch of passages and re-read chapters several times over. I love hem even more if it's told from the point of view of multiple characters or we have a ensemble cast with no real MC. I also love historical fiction and magical realism.
My favorite books of all time are 100 Years of Solitude and A Brief History of Seven Killings if that helps with gauging my taste.
