Three years ago, Earth was conquered by a force of robots from a distant world. They have one rule: STAY IN YOUR HOMES Step outside and you get one warning before you're vaporised by a massive robot Sentry, or a crawling Sniper, or a flying Drone. That's if the vast Cube doesn't incinerate you first. But Sean Flynn is convinced that his father - an RAF pilot who fought in the war - is still alive. And when he and his gang figure out a way to break the robots' curfew, they begin an adventure that will pit them against the might of the ROBOT OVERLORDS. This fast-paced, thrilling novelisation is based on the hit British film starring Sir Ben Kingsley (IRON MAN THREE), Gillian Anderson (THE X-FILES) and Callan McAuliffe (THE GREAT GATSBY). A perfect companion to the movie, it expands on the story with additional action, characters, and a special peek behind the scenes.
