Finding My Way Back Home

Camila is Liam's brother who was kidnapped at a young age and was adopted into another family. She was well loved and cared for by her new family but she misses her birth family that she doesn't really remember too much except for bits and pieces here and there. But one day after she runs into the one direction boys out at the park she drops her one and only family photo she had of her birth family that she carries everywhere and the boys find it and recognise the family in the photo and seek answers.
