Perhaps Deserving of 5-Stars, but Not Quite
This is truly a SciFi book, but different from what you might normally want or expect to read. For instance, it does have a space-related angle, but it’s pretty nebulous and hard-to-believe. This book is, instead, more of a Sociological story, and takes broad swipes at sex, race, and many other social conventions.
I feel that the ending was simply a way to truncate and end the story, which is a shame.
