Can you suggest me some fiction books to help me ponder more about life, how you could grow from that (like personal growth through reading), and can really make you question some stuff like (existence, life, questions unanswered, etc)?

I'm interested in delving into this type of literary genre. I want to see life from a different perspective, more so than the typical "life goes on" lifestyle and worldview. Like, I want to ponder beyond the passive and carefree perspective on life. And it could perhaps make me ask questions about existence, make me grow from reading, and all-in-all, a must-read.
