Holly's mum is a hoarder, and she is fed up with being picked on at school for being weird...and having the wrong clothes...and sticking out. All she wants is to be invisible. She loves swimming, because in the water everyone is the same. Ed goes to the swimming pool because everything else in his life has changed. In his old life he had money; was on the swim team; knew who he was and what he wanted. In his old life his dad hit his mum. Holly is swimming in one direction and Ed's swimming in the other. As their worlds collide they find a window into each other's lives – and learn how to meet in the middle.
