Crossing lines (one direction)

Okay let me just say I suck at weighing descriptions so yea here goes. So two girls get into a plane crash on there way to London, one of them ends up going to live with the paynes but Liam doesn't like her so yea, she ends up on tour with them and eventually all her secrets come out but will the boys a pet her for who she is or will they discard her like her mum did.
