What are some of the most life changing books for you? Fic and non fic

Trying to get back into reading but I want it to impact me, mainly positively. Some recs that shifted your perspective, books that you got so absorbed in the story and what happens next (any genre besides horror), things like this are what I want to get into. What were some books like that for you?

Thanks in advance, I look forward to looking into recommendations!!!
