Three best friends, with very different lives, are linked together by one thing, or should I say, five things - One Direction. Firstly, Ashlyn Tomlinson, who has an easy-going life - or as easy-going as it can get, being the sister of a member of one of the world's biggest boy-bands. But it's not all easy when the boy she loves, loves someone else. Secondly, Arielle, who moves into the 1D household when her parents go to the States, in search of a fresh start to try to move on from her past. And, lastly, Camilla - the Oxford University student, also known as Harry Styles' girlfriend, who makes a shocking discovery that could change her life, for better, or for worse. Join their whirlwind journey, full of laughter, secrets, relationships, friendships, tears, happiness and heartbreaks.
Ashley Styles is Harry's sister. She hasn't seen her little brother in over five years. She arrives in London, excited to see Harry, but there's something else on her mind. And when a certain blue eyed british boy begins to fall for her, things get even more complicated. But as Louis says: live your life for the moment, because everything else is uncertain.
