Nash Grier's Twin//Jack Johnson Fanfic

Sarah Grier is Nash Grier's twin sister. I guess you could call her normal. She attended school everyday just like everybody else. Except for a dark secret that she's always kept to herself. She never was well liked at school, until she got the app Vine. Now that she's famous, she has been invited to a tour called Magcon with her brother and 8 other guys. What happens when 3 of them fall for her, but she only falls for one?
