Mortal Engines (Predator Cities, #1)

by Philip Reeve

“The Guild of Engineers plans further ahead than you suspect. London will never stop moving. Movement is life. When we have devoured the last wandering city and demolished the last static settlement we will begin digging. We will build great engines, powered by the heat of the earth’s core, and steer our planet from its orbit. We will devour Mars, Venus and the asteroids. We shall devour the sun itself, and then sail on across the gulf of space. A million years from now our city will still be travelling, no longer hunting towns to eat, but whole new worlds!”
