Charlie Hemmings is your average teenage girl. She has blonde hair and blue eyes and is rather pretty. Did I mention she has a twin brother named Luke? That's right, Luke Hemmings. Luke loves to sing and joins up with his mates, Calum and Michael, to become a band called '5 seconds of summer'. Charlie becomes great friends with the boys and everything is simple. But then Calum kisses her and things get strange. Not to mention the new band drummer, Ashton. Ashton is one of those hot senior boys and he ends up spending a lot of time at the Hemmings' house. Charlie starts to like Ashton and she thinks he feels the same way.. But how can she be sure?
