“Book/series about an antihero with a redemption arc”

Hello, I am trying to find recommendations on a story that follows an antihero with a redemption arc. I’m searching on behalf of someone else because they are having a hard time finding a story, and I thought maybe some avid readers would have some recommendations 🙂 I tagged as fiction because I thought maybe that would be the best option, but any recommendations at all would be appreciated!
