DNA. Free will. Secret government projects. That was just the beginning. For centuries mankind has been living under the assumption that they were free. It's time they knew the truth. They were created for a specific purpose: to be soldiers, to lead armies. For two decades they were trained for that purpose-physically, mentally, and emotionally. But something went wrong. The two soldiers disappeared, and the project was terminated. Now, centuries later, it is time for Sentry and Sentinel to meet again in an encounter that will decide the fate of humanity. For many people it will be a battle that will be the culmination of many years of intensive work, while for others it will be a sudden and nearly incomprehensible change: an FBI Captain will be forced to confront his prejudices; a reporter will discover a terrible secret from her childhood; a Runner will lead a revolution; and a president will have to face the truth about himself. .For some it will mean betrayals. Others will become heroes.
