This is a rather unusual book: it has the coming-of-age material, and some love story, and there are aliens, and adventures, and diplomacy and war. But at the center of the story there is a language, an alien language that no single human can speak and special pairs of "ambassadors" are grown and trained to use it. I could never imagine, that Ferdinand de Saussure's linguistic theory can be turned into an interstellar adventure narrative #bookclub
