The Zodiac’s newest recruit leaves London behind to find an elusive inventor, but his target proves far stranger. Ash discovers an aloof host, bright lights in the sky, and a woman who is either an innocent prisoner…or completely mad.

Together, Ash and Nora hold the key to a conspiracy between two warring nations. In the midst of danger, they find an improbable love, and the chance for a new future…if they live long enough to reach it.
