Query: On the level of Left Hand of Darkness

This book deals with the complex issue of what would happen if the missionary period were to reoccur. It could, on another planet, and it would be with modern people in a modern context. Mary Doria Russell poses that problem, and does not give it a Hollywood ending. Her characters are believable and likeable. She draws from a vast store of knowledge and interest in the missionary period of the Jesuit order, in astronomy, and in many other areas. Her sense of history adds as wonderful a dimension as Ursula Le Guin's sense of anthropology does to her writings. It is a book that will develop an ever expanding following.
