For Rachel Boyd, documenting the lives of indigenous people in the Venezuelan rain forest was meant to be the chance of a lifetime. When she witnesses and films the organised massacre of an entire village it turns into a fight for much more than her own survival. In London, there are two weeks to go until the climate-change summit at Chequers. For Rachel's father, Mark Boyd - ex-husband, ex-activist, ex-green-advisor to the Prime Minister - a chance for redemption. Then a car-bomb destroys the Piccadilly underpass. An unknown group of eco-warriors claims responsibility. 'A taste of things to come,' they warn, unless the new coalition government immediately implements the environmental policies they promised. But nothing is quite what it seems. A terrifying conspiracy is unravelling, reaching from the highest tiers of Whitehall to remotest Venezuelan rain forest. And Mark Boyd can blow the whistle. But he needs his daughter's help to do it. Can she get to London before her enemies get to her?
