It's about a 18 year old girl called Sophie and she has recently lost her parents and has no other family, and one day she's being chased by a creepy man and falls unconscious and she wakes up to be in One Directions tour bus on the way to the hospital. Niall Horan likes her and asks her out she says yes and they are very happy when suddenly something comes upon them.... Can she face it and will they be together forever and have a gorgeous family or will something stand in the way??....
