The Mortal Engines series started with my first novel, Mortal Engines, back in 2001. I then went on to write three sequels, Predators Gold, Infernal Devices and A Darkling Plain.
Together the books cover nearly twenty years in the history of the Traction Era, a far-future age when cities move about hunting smaller mobile towns and dismantling those they catch for their raw materials. Airships ply the skies, amphibious limpet-submarines lurk in the oceans, and dangerous bits of technology left over from a long-ago war lie waiting to be discovered and put to use in the looming conflict between the cities and their anti-tractionist enemies.
I thought I’d finished with that world when A Darkling Plain was published, but new ideas kept bubbling up, and in 2009 I returned to the dawn of the Traction Era in a prequel, Fever Crumb, about a girl living in London shortly before it starts to be rebuilt as a mobile city. Fever went on to have more adventures of her own in my next book, A Web of Air and Scrivener’s Moon – further books expanding the Mortal Engines world.
