In the last book of the trilogy, things are coming to a head in the conflict with the Others. At the same time, Bob continues to live in android form among the Deltans, something of a hermit from his own kind.
Mr. Taylor does not lose steam at the end; rather the opposite. This volume brings things to a satisfying conclusion while continuing the thematic exploration of humanity, mortality and the nature of loss. There is also significant discussion on the duty of an individual to society. Is a Bob, or any other individual for that matter, honour bound to serve humanity just because he or she has the ability?
