Prosperity, 1863: a lawless skytown where varlets, chancers, and ne’er-do-wells risk everything to chase a fortune in the clouds, and where a Gaslight guttersnipe named Piccadilly is about to cheat the wrong man. This mistake will endanger his life . . . and his heart. Thrill! As our hero battles dreadful kraken above Prosperity. Gasp! As the miracles of clockwork engineering allow a dead man to wreak his vengeance upon the living. Marvel! At the aerial escapades of the aethership, Shadowless. Beware! The licentious and unchristian example set by the opium-addled navigatress, Miss Grey. Disapprove Strongly! Of the utter moral iniquity of the dastardly crime prince, Milord. Swoon! At the dashing skycaptain, Byron Kae. Swoon Again! At the tormented clergyman, Ruben Crowe.
