The hunt escalates up the chain of power: American billionaires, London and Zurich financiers, and then sitting world leaders. Sentinel wasn't an American operation that went global ? it was global from the start, and America was just one theater. With Claire and his network beside him, John dismantles the machine node by node across the globe, and every victory reveals a larger silhouette above. At last: one name, one face ? the last person at the top. And John goes after them. The ninth explosive volume of The Authorization. "If you're hearing this, I didn't make it home."
