Ella’s friends had told her that the country would be safer than the city. They were wrong. Now they’re dead and Ella’s all alone–alone, that is, except for her silent rescuer, Scarface. But she doesn’t even know if he’s a kid or a grown-up. Back in London, Ed is determined to find Ella and keep his promise to Small Sam that he will reunite sister and brother.

Will anything be able to stop the invading horde?
