Barry Mundy has brown skin and blue sin and, at seventeen, those two colours define his life. When he gets a job at the Croc-Jumping cruises on the Adelaide River in the Northern Territory, he carries a list of names of the men who could be his father. They're all dark for different reasons and Barry hungers to know whose blood flows inside him. All he sees when he looks in the mirror is a brown mask that hides a blue secret.
