Caleb is a modern African tragedy. It is a tragedy arising from the terrible wars which sweep the continent, and out of the clash of cultures and beliefs. Caleb Jordan is born into a family of pastors. He becomes a servant of God, suffers a devastating failure of a marriage and chooses to start a mission in deep rural Africa. He has much success but lives constantly in the shadow of a dark reality of ancestor worship and witchcraft and the challenge they bring to his faith. The setting is the Nuanetzi River in the Gaza Province of Mozambique, where circumstances from the past bring to a head a deadly clash of personalities and beliefs.
