'Before you embark on a journey of revenge, first dig two graves' - Confucius

In the 91 hours following the brutal kidnapping of his wife, FBI agent Pendergast does everything in his power to find her. But it's too late. And a shattered Pendergast retreats to his New York home where he shuts the world out.

Then a string of bizarre murders erupt in Manhattan's hotels, and Pendergast realises they're a deadly message from the kidnappers. Filled anew with vengeful fury, he tracks them to the dark forests of South America, where he is faced with an old evil that threatens the world as we know it. . .
