Pia has lived at Kauri Haven since fleeing imprisonment in Australia for seditious activities, through the intervention of Kaire, the man she calls the Skyman. On the first anniversary of her mother Sannah's death, Pia's fragile composure threatens to shatter upon receiving disturbing news from the Brown Zone in apartheid Australia. Five Line Leaders have been incarcerated in the infamous prison complex beneath the central desert. An ingenious plan is undertaken to free the women, but from the moment Pia meets the youngest, Yuki, she feels troubled. Her fears are compounded when Kaire receives unexpected orders, which threaten his survival and that of his Sky friends. Can Pia assist Kaire in his preferred mission, without compromising her position as an authorised refugee?
