Elijah is nothing special. He's just a skinny kid doing his best to stay one step ahead of starvation and the people who would have him locked away in a labour camp - just another Runner. But what he stumbles upon in a forest in Hampshire shows him that the harsh world he knows will become an even more sinister place, unless he can stop it. As past and present and parallel dimensions collide, freedom becomes the last thing on his mind as he is suddenly faced with a battle to save his world from extinction. But before Elijah can find the courage to be the hero the world needs, he must banish his own demons and learn to trust his friends. And all the while, the sinister figure of Maxwell Braithwaite looms, his path inextricably bound to Elijah's by a long dead physicist, and hell bent on stopping Elijah, whatever the cost.
