One plus one. A simple equation but the solution isn't always as easy.
Marlie Rhodes had never been interested in boys. She was one of the few girls out of her group of friends that preferred curling up with a book than going out with a guy. That was at least until a certain curly-haired boy forced his way into her life, possibly causing more problems than he solved.
15 year old Marlie doesn't have it easy and the only person to make her happy is her 16 year old boyfriend Harry Styles. That is until things change and some things get herder. How will Marlie handle her situations?
