Human Avice Benner Cho grew up in a colony on backwater Embassytown. She left the planet to travel in space, but now accompanies her linguist husband Scile back to her home where he plans to study the language of the sentient native population the Ariekei AKA Hosts; she never learned their language though her smile helped her get by. She is not alone as the outsiders cannot comprehend the language of the morally driven Hosts so linguist ambassadors were created to communicate with the species.
However, two events shake the value system of Host society. First an Ariekei learns to lie; an unheard of shattering event. Second two new Ambassadors arrive whose respective sounds produce an odd yet deep physical impact on the Hosts. Their pure society, which survived the colony, is undergoing radical change as Avice tries to help.
This is a great science fiction thriller that takes a profound look at communication through the Host who are wired differently from the humans; sort of mindful of the Autistic Spectrum while the first lie will remind readers of the movie The Invention of Lying in an Avatar realm. The cast is solid especially the fascinating Host who find their world being radically changed when their Language is assimilated by the space travelers. China Mieville provides a thought provoking look at the relationship between a society's values and its language as each shapes the other.
