Lily struggles with an apathetic mother, a domineering grandmother and the shifting alliances of her schoolgirl friendships. She soon develops a brittle self-esteem and obsesses over the one aspect of her life that she can control – her body. A story of secrets, warped friendships and addiction, and how families guard their secrets to keep up appearances – with disastrous consequences.
