The subject title refers to both this book itself and the series as a whole. The entire drama with Nicole grew and evolved to become one of the central foci of the book. For that awesome scene at the end - and the realization of the meaning of the Universe - it almost deserves a "*****". But Nicole's other self seems so human like in her wants and desires. We got to this point and the authors seem to be saying, "OK, we know the secrets of the cosmos. What do we do now?"I would have loved to have seen this idea in the hands of a Frank Herbert or a Pamela Sargeant.
