The second book in the award-winning MORTAL ENGINES quartet. Far above Anchorage, a tiny aircraft falls from the sky. Having fled from London in MORTAL ENGINES, Tom and Hester seek refuge in a city devastated by plague, haunted by ghosts, and filled with deadly secrets... MORTAL ENGINES launched Philip Reeve's brilliantly-imagined creation, the world of the Traction Era, where mobile cities fight for survival in a post-apocalyptic future. Now, in time for the film debut, the critically acclaimed MORTAL ENGINES quartet is repackaged with a fantastic and eye-catching cover featuring new artwork.
