What are some compelling novels that explore the theme of identity and self-discovery?

I'm looking for novels that delve into the theme of identity and self-discovery, showcasing characters on a journey to understand themselves better. I recently read "The Alchemist" by Paulo Coelho, which beautifully captures the quest for personal legend and fulfillment. I'm particularly interested in stories that highlight different cultural backgrounds or unique perspectives on identity, whether through coming-of-age tales or transformative experiences.

If you have any suggestions that offer rich narratives and thought-provoking insights into what shapes who we are, I would love to hear them!
