Skyshaker (The Great Iron War, Book 3)

The Resistance takes to the clouds aboard the Skyshaker, the newly-completed airship aimed at dominating the heavens, when the land far below has become a hellish place ruled by demons. General Rommond fixes his attention on the city of Blackout, the old capital of the world, controlled by the Treasury, who are themselves controlled by the ruthless Regime. The skies above that city will no longer hide in smog; fire and fury will light up the sky. That centre of the old civilised world will either shift allegiance to the Resistance, or it will burn to the ground. Yet there are always others who will resist the attempted change of power. From sky pirates and mob bankers to the feared mechanical men of the Iron Guard, Jacob and his new family of freedom fighters will face greater challenges than they have ever faced before. As bombs drop from the sky like the iron tears of gods, there are other revelations that will shake the foundations of everyone struggling to save humanity.
