Looking for books with unforgettable characters, who stayed with you long after finishing.

One of my favorite things about reading is when a character sticks with me long after I’ve closed the book. Whether they’re deeply flawed, inspiring, quirky, or just so well-written that they feel real it’s those characters that really make a story unforgettable.

I’m looking for recommendations for books with characters like that.

For example, I’ll never forget Atticus Finch from To Kill a Mockingbird

Who are some characters you’ve loved or admired in your reading, and what books do they come from? Thanks in advance for the suggestions!
