The second book in the Lords of Creation series. This one deals with Mars. Here we have a much more advanced race of people. Mainly in biological sciences they create most of their tech from living machines. They are a people that are somewhat different genetically from Earth humans but still related. They also are a race that seems to have little curiosity and believe everything that has been worth discovering has already been done. So their society is stagnant and they show little interest in the Vas-Terrain or people from the Wet World.
I think this was better than the first book. The Martian society had a fascinating complexity to it. Plus you had the good old fashioned adventure with flying ships, swordfights ,intrigue and romance. Sterling left open some new story ideas at the end for the ancient technology activated by the invisible crown opens stargates on all three worlds to a new world. So there are new worlds to explore and maybe someday Sterling will continue with this fascinating look at a reality where Mars and Venus were made habitable by a mysterious ancient alien race.
