In the untamed outback of Western Australia, the Blake sisters are together again despite what seemed like insurmountable odds. For Cassandra, reunited at last with the man she loves, the Swan River Colony is a refuge that seems like a miracle after her ordeals. Two of her sisters have fallen in love with their new way of life. But then a messenger arrives from faraway England and it is the fourth sister, Pandora, who jumps at the chance to make her way back to the Lancashire moors she misses so badly.
