This is the fourth and last book of the Spectrum Chronicles. As a young person, it seemed AGES before this book was FINALLY published and we readers knew what would happen between Consuela and Wander.
This last book has Captain Arnol and Pilot Dunlevy detained by Hegemony forces while Tucker, and Guns take Rick and Consuela (with others and equipment) as a mercenary group looking for work. They find a caravan headed for Yalla, but the owner's son has misgivings. He challenges Rick to a low gravity speed race (think snowboarding on a desert planet). The book gives a detailed description of this, which Rick survives.
The mercenary unit earns their keep when bandits attack the caravan. Consuela is able to find the Citadel. Wander realizes the Citadel's weakness and both he and Digs are rescued and therefore he is reunited with Consuela.
The epilogue has both Rick and Consuela receiving some advice from Daniel and Bliss regarding what their respective paths as Christians might be. Consuela takes a roller coaster ride back to be with Wander, but we are not told what Rick's path may be.
As a young person, this seems a very fitting end to the limited issues brought up. As an adult, I wonder if this is more a jumping off point to a larger series (struggle between the Hegemony and the planets they have oppressed).
