looking for a book that completely pulled you into its world

im looking for one of those books that completely takes over your brain for a while. the kind where you stop noticing time passing when youre reading and suddenly youre emotionally attached to fictional people like theyre real. i dont even care that much about genre right now i just want something immersive with characters and a world that feel alive
bonus if its the type of book that stays in your head after you finish it and leaves you feeling weirdly empty because nothing else compares for a few days. i miss that feeling of getting completely lost in a story and thinking about it nonstop when youre not reading. what book did that for you recently or even years ago that you still havent stopped thinking about?
