Y/N Stark, Tony Stark’s younger sister, is an exceptional fighter with the rare ability to heal injuries and instantly sense what is wrong with someone. When she joins the Avengers, Steve Rogers falls hopelessly in love with her, but their growing relationship creates one major problem: Tony. While Tony and Steve constantly argue and compete, they would both risk everything to protect Y/N—and each other. When Y/N realizes Steve’s feelings are mutual, Steve must fight not only for their love, but also to convince Tony to let him date his little sister.
