In the heart of the jungle lies a powerful secret. A secret thousands die for every year. A secret that men will kill for. They hoped for the trip of a lifetime. Now they are hours from death. Mark and Melanie Bridges are lost in the world's most hostile forest. Their guides are dead. They have no shelter, no water, no hope. Then, as the shadows lengthen, they stumble on the wreck of a crashed helicopter. The pilot and passenger are bones, their doomed mission to this remote and dangerous land, uncertain. But the skeletons have left behind both good and bad: vital supplies to keep the pair alive. And a mystery that threatens to kill them. Soon nowhere is safe. Not even the civilisation they left behind. And as the clues unfold, so begin the lies, the blackmail, the kidnapping and murder. Because Mark and Melanie's secret is far bigger than they ever imagined. Bigger too than the jungle that hides it, and the ruthless killers who pursue it. It is a secret that commands the power of life and death. A secret that will change the world forever.
