After taming the Temple of Ishtar, rebel airship captain Charlotte Frost and her clockwork courtesan, Arslan Tash, have a monumental task ahead of them. They must protect and defend the Temple from Gabriel Harper, a mysterious alchemist who has designs on the Temple and the secrets therein.

The problem? Charlotte is attracted to Gabriel. She must overcome this attraction to the enigmatic man while simultaneously orchestrating a defence against the Matriarchy, who plan to break into the Temple and claim the fabled Engines of Eros, power cores that contain the very essence of the gods.

Can the intrepid aviatrix resist her hungers for Gabriel long enough to keep the Engines out of the hands of those who would abuse their power?
