This is the only Kate Wilhelm book that I've read (and am apt to read) because it's a Hugo and Nebula winner and is thus a required read for anyone who is a student of the genre.The book hooked me with the first few chapters and I was really excited to find out what happened with the details of the colony and cloning. But the story soon became mired down in liberal aspects of communal living and "free love." It's clear that Ms. Wilhelm was influenced by the 60s movement when she began writing this (probably) in the early 70s.All in all not a bad book. I enjoyed it. But it's marginal science fiction at best that got lost in the later 2/3rds.
