Jack and his friends are in a race against time to save the remaining inhabitants of a postapocalyptic London from a nuclear bomb.  Two years after London is struck by a devastating terrorist attack, it is cut off from the rest of the world, protected by a large force of soldiers (known as Choppers) while the rest of Britain believe that their ex-capital is a toxic, uninhabited wasteland. But that's not true. Jack and his friends know that the truth is very different--and incredible: the few remaining survivors in London are changing; developing strange, fantastic powers; evolving. And the Chopper force guarding London is treating the ruined city as its own experimental ground. Now, Jack's powers are growing. His friend Lucy-Anne's powers are developing too, and Nomad--that mysterious woman who started it all--is close by.
