Yarrow is stifled and hates his life. he seems to really enjoy his work, correlating and researching languages. He gets an opportunity to go into space when a spaceship returns after finding a new planet with intelligent life. Freed from the dreary marraige, Yarrow still contends with his gapt, or the man who watches him almost constantly, but is otherwise enjoying learning about the wog language and culture. Then, while looking at a wog temple, Yarrow sees a humanoid female, Jeanette. The title gives away that they fall in love but doesn't give away the best parts of the story.
The culture is pretty frightening. I see it as all the things the religious right wants in the US, taken to the extreme of law. The biology is a bit sketchy but this book was written in the early 1950s. I give it a 5 and recommend it if you like old science fiction.
