I'm beginning to notice a pattern; I'm giving five stars to every Sturgeon book I read, it's becomming a habit. But what else can I do but acknowledge his genius?
This is a book of three parts, each part a process of discovery for the reader and at least one of the characters involved who are each trying to find something out about themselves, come into themselves in some way.
I've also said before that he seems so far ahead of his time and it once again becomes apparent in this book. It is a million miles away from most other SF being written at the time. Somewhat disturbing and deeply thought provoking is a good way to describe this story.
