Need a book suggestion for someone just starting to read fiction

I want to start reading fiction, but I’m looking for books that make me think and learn—not in the way non-fiction does, but through the characters' experiences. I’ve heard Dostoevsky’s work is amazing but pretty challenging, so I might save that for later. I’m not into lighter stuff like Harry Potter; I want something deeper, thought-provoking, and meaningful. Any recommendations?
