What is the point of Volume III?

Not the message, since that's cheezy. But the meaning--created by the act of reading. The reader has been seduced by Santa Zita in  Vol. I (City On the Hill) and betrayed in Vol. II (1989.) If CotH is Star Wars, and 1989 is the Empire Strikes Back, does that mean Vol. III is Return of the Jedi, with all that that entails (Ewoks, Darth Vader suddenly turning good, etc.)? If CotH is thesis, and 1989 antithesis, then Vol. III must be synthesis and integration. Both for the characters, but also for the reader's relationship with the writer, and the work.
