Like Riding A Motorcycle, Book 13 in Cocker Brothers, Sofia Sol:

I was raised to be like my parents - Jett and Luna Cocker - a hero and a rebel. I'm the leader of the kids who grew up in The Cipher's M.C., who, now as adults, save the innocent. But we are forbidden to think of each other as anything other than blood, though I share none with them. Can I help it if I want to break down locked doors?
