A mothballed power station, a teenage drug dealer and a cult. The mix is electrifying. Young James Bond meets Breaking Bad... A counter-terrorism operative shows up tortured to death. An elderly prof goes missing. An eco-cult is recruiting at a weekend concert for young people at Battersea Power Station. A teenage felon's got to make a simple swap: Some photos for his freedom. Only he's trapped inside Battersea Power Station. No swap. No way he can tell anyone about it. And the dawning horror that this time the missing and the dead will bring England to its knees. He's got his GCSEs, his guitar, and a grasp of engineering. That's got to be enough. To free himself. And save London.
