To us it seems like a mad combination of heaven and hell. To them, it seems like normal life.And in this world, Mycroft and Carlyle have stumbled on the wild card that may destablize the system: the boy Bridger, who can effortlessly make his wishes come true. Who can, it would seem, bring inanimate objects to life...
