Brooke was abandoned by her family. She'd lived on her own in London for her entire life, and now she was turning nineteen in three weeks. She meets a band at a hotel that she frequently sneaks into night after night. One bandmate is apparently her brother, but neither of them remembered each other, considering she was sent away at four months old. Her brother is from the world-famous boyband, One Direction. He lets her live with him, and she begins to become best friends with one band member, practically a daughter of another, a partner-in-food with the blondie of the group, the obvious sister of the oldest boy, and she slowly falls in love with one of these charming whacko-singers.
