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.
