South Africa, 1820. When Ann Waite discovers a battered longboat washed ashore in Algoa Bay, she is stunned to find two survivors: a badly scarred sailor and a little boy. As the man walks away into the morning mist alone, refusing to take the child - Harry - with him, Ann is left with no choice but to raise the boy as her own. After two years of disaster and hardship in the African interior, desperation drives Ann and Harry back into the path of the mysterious shipwrecked man. Ralph Courtney has recently escaped from Robben Island and is determined to seek his fortune in Nativity Bay, the hidden harbour that his father told him about when he was a boy. But it isn't long before Ralph, Ann and their fellow settlers learn that Nativity Bay now lies on the borders of a mighty kingdom, where the warrior king Shaka rules.
