At the request of the Earl of Kensington, Donovan Tisdale attends a mind-expanding presentation by Richard Sandominus Flynn, the Minster of Steam-based Sciences. Flynn reveals the next step in steam-based power-flights to the moon and far beyond conducted by mechanical men.

The attraction between Donovan and Flynn ignites from the moment they meet and follows them through the dangerous political climate of Her Majesty's jeweled city as dark powers seek to dismantle the clean-based power poised to send humanity to the stars.
