All this is not really a summary of this third book.  To tell you the plot would ruin any suspense I could possibly hope for.  Sorry, but I've used this space to talk about something that concerns me ...it doesn't concern me more than anything else in the whole world, and I'm not trying to isolate only the issues I use as examples, they are just the current ones as I am typing.  But now, I will attempt to finally give you a quick summary of the stories that are in these books.  This third book brings sort of a conclusion to the life of Maggie Major ...described in book # 2, entitled, The Curious Whether and How.  Ruth, whose life is most prevalent in book # 1, entitled, So Loved ..., makes a decision that sort of directs the path of her life from this point on ...into the fourth and final book, entitled, The Evolution of Confusion.  So this third book creates a sort of happy ending for one, and a workable path for another.
