In this 1D fan-fiction, frumpy and drab Caroline Cooper, Harry Styles' "greatest" fan, lives with her mother in London who is the wardrobe coordinator for One Direction. To break her fangirl attraction to Harry, her mother sends her to her father's home in New York City, where Caroline experiences big city life and big changes (physically and mentally) for herself. Four months later she returns to London, where Harry sees her in a different light, but another band member becomes involved in a twisted plot of romance and deception.
