When Bea Hanlon follows her preacher husband Max to a remote island in the Pacific, she soon sees that their mission will bring anything but salvation... Advent Island is a place beyond the reaches of Bea`s most fitful imaginings. It`s not just the rats and the hordes of mosquitos and the weevils in the powdered milk. Past the confines of their stuffy little house, amidst the damp and the dust and the sweltering heat, rumours are spreading of devil chasers who roam the island on the hunt for evil spirits. And then there are the noises from the church at night.
