Avery Rose Horan was so proud of her twin brother, Niall, when he went on the X Factor. She had convinced him to go on, and now that he was internationally famous, she was so happy she'd done it. She met his bandmates, Liam, Zayn, Harry, and Louis, when they were first put together, since she and Niall had skyped every week he was on the show. Now, all of the boys were her best mates. But a certain boy wanted to become more than that.. Of course, Niall and Avery were both oblivious to just about all human emotion that required too much thought, and neither of them noticed how much Harry fancied Avery. So when Niall invites Avery to come with them on their American tour, she accepts graciously, and Harry is happier than he's been in months. It opens up so many opportunities for not only Harry, but some other boys as well.. Will Avery realize how much Harry fancies her in time? Or will she unknowingly break his heart?
