Maci Payne is the most popular girl in school. She gets good grades and is captain of the cheerleading squad and softball team. She has lots of friends and is dating the school football star. Life is perfect. Except for one thing. She has a brother that she never told anyone about. Liam Payne of One Direction. He knows she exists and she knows all about him but they never talk except for a birthday card and Christmas present. What happens when they have no choice except to come face to face? Will they get along like a happy family or will the past be too much for them to handle? Let's not forget what happens when we add in the rest of the band and potential new love interest?
