Sephen Hunt's Jackelian series of futuristic steampunk tales includes The Court of the Air and The Kingdom Beyond the Waves. He also founded SF Crowsnest where over 100 of my book reviews have appeared.
Q. Would you like to live in a court in the air or in a kingdom beneath the waves?
A. Well, my answer to that one has to be 'The Court of the Air' - especially if I was running the joint, as I could sit up high watching everyone and ordering the arrest without trial or murder of anyone who did bad stuff down in the world... and it doesn't get any better than that.
