An airborne invasion. A friend turned traitor. An empire in danger. Welcome to the second book in the thrilling steampunk series, Iron Sky! Step into an alternative nineteenth-century England filled with giant airships, steam-powered automatons, aerial carriages, floating cities . . . and a new kind of secret agent. As Napoleon’s forces mount a full-scale invasion of the country, Lady Arabella West and her mechanical sidekick Miles must face two deadly enemies: the Equestrians—a terrifying army of iron centaurs—and, worse yet, one of Arabella’s own Sky Sisters, who has turned traitor. Can she and Miles save the British Empire from the forces that would destroy it?
