In this genre-twisting novel, infamous necromancer Johannes Cabal, after beating the Devil and being reunited with his soul, leads us on another raucous journey in a little-known corner of the world. This time he's on the run from the local government. Stealing the identity of a minor bureaucrat, Cabal takes passage on the Princess Hortense, a passenger aeroship that is leaving the country. The deception seems perfect, and Cabal looks forward to a quiet trip and a clean escape, until he comes face-to-face with Leonie Barrow, an enemy from the old days who could blow his cover. But when a fellow passenger throws himself to his death, or at least that is how it appears, Cabal begins to investigate out of curiosity. His minor efforts result in a vicious attempt on his own life - and then the gloves come off.
