On a cold January morning, the United States awakes to discover that an old enemy, one long believed dead and buried, has crawled out of its grave to lay siege to the world's only superpower. With the discovery that enhanced Soviet-made suitcase nukes have been secreted in America's major cities, President Jack Rutledge gathers his National Security Council to weigh the feasibility of a first strike against the Russian Federation. There's only one problem. For over two decades, the Russians have been funneling international aid money into a top secret air defense system, which has just been brought on-line and which will render any conventional attack upon their country utterly ineffective. After exhausting all of his other options, and with Soviet sleeper agents preparing to detonate their deadly payloads across the United States, the president turns to the nation's final hope, ex-Navy SEAL and Secret Service Agent Scot Harvath. Assigned to a covert section of the Department of Homeland Security and charged with defending the nation against all foreign aggressors by any means necessary, Harvath finds himself hand-picked by the president to unravel a timed conspiracy that has already shattered the fragile peace between the world's nations and which, if successful, will leave the United States in smoldering ruins.
