In a faraway corner of a ruined world, a mysterious boy is building a flying machine. Birds help him, and so does a beautiful, brilliant, half-human engineer called Fever Crumb. But powerful enemies stalk them - either to possess their revolutionary invention, or to destroy the secrets of flight forever.

The author of the best-selling and critically beloved Mortal Engines quartet has written a stunning, stand-alone prequel. London is a riot-torn, ruinous town, clinging to a devastated landscape and hiding an explosive secret. Is Fever, adopted daughter of Dr Crumb, the strange key that will unlock its dangerous mysteries?

In a land once known as Britain, nomadic tribes are preparing to fight a terrifying enemy - the first-ever mobile city. Before London can launch itself, young engineer Fever Crumb must journey to the wastelands of the North and seek the ancient birthplace of the Scriven mutants. The seventh awe-inspiring adventure in the MORTAL ENGINES series.
