Now, Taziri is the only pilot left to help the marshals chase the killers across the skies of Marrakesh. The investigation ranges across the country on steamships, atop racing locomotives, and into ancient tombs. Taziri discovers a corrupt doctor performing hideous experiments, hiding lethal weapons inside the killers' bodies using Taziri's own inventions. And with assassins in every shadow and riots on every street corner, Taziri quickly learns to defend herself as only an engineer can - with her machines. The marshals have one other problem: they're men. And in a country where women control the government, the military, and the most powerful industries in the world, Taziri has a clear advantage. But despite all her efforts, her country's only hope for survival may be an exiled Incan princess riding a giant eagle, a dashing swordsman who talks to ghosts, and Taziri's airship Halcyon plummeting out of the burning sky. less
