Name a book you believe everyone needs to read! It can be about any topic, author, or genre. <3

I'm trying to get a compiled list of books that people believe everyone needs to read in their lifetime. I'm hoping that by asking on multiple platforms, I'll be able to make a comprehensive list.

I want to expand and try new genres and topics that may intrigue me. I would love to do book reviews on a blog, but I need help getting started by diversifying books that others are into.
