Lily turns sixteen with two very different sides to her life: school, where she is badly bullied, and home with her mum and dad, warm and comforting but with its own difficulties. After a particularly terrible bullying incident, Lily's dad determines to give his daughter the tools to fight back.

Introducing her to boxing, he encourages Lily to find her own worth. It is both difficult and challenging but in confronting her own fears she finds a way through that illuminates her life and friendships. Meeting Rose, and seeing that there is another world out there, enables her to live her own life fully and gives her the knowledge that she is both beautiful and worth it.
