Straight-as-an-arrow special agent Kate O'Hare and international con man Nick Fox have brought down some of the biggest criminals in the world. But now they face their most dangerous foe yet - a vast, shadowy international organization known only as the Brotherhood. Directly descended from the Vatican Bank priests who served Hitler during World War II, the Brotherhood is on a frantic search for a lost train loaded with 30 billion in Nazi gold, untouched for more than seventy-five years somewhere in the mountains of Eastern Europe. Kate and Nick know that there is only one man who can find the fortune and bring down the Brotherhood - the same man who taught Nick everything he knows - his father, Quentin. As the stakes get higher, they must also rely on Kate's own father, Jake, a retired Special Forces operative who proves to be every bit as stubborn as his daughter. These four have all the skills needed to complete the mission, if they can just survive each other. From a remote monastery in the Swiss Alps to the lawless desert of the Western Sahara, Kate, Nick, and the two men who made them who they are today must crisscross continents in a desperate scramble to stop their deadliest foe in the biggest adventure of their lives.
