America's worst nightmare has just become a brutal reality. The most unlikely terrorist enemy of all now holds a knife against the country's throat. With both diplomatic and conventional military options swept from the table, the president of the United States calls upon America's only hope, Navy SEAL turned Secret Service agent Scot Harvath. With the fragile peace between the world's nations shattered, Harvath must unravel a brilliantly orchestrated, fiendishly timed conspiracy intent upon bringing the United States to its knees. Teamed with beautiful Russian Intelligence agent Alexandra Ivanova and a highly trained CIA paramilitary detachment, Harvath races from the corridors of power in Washington, D.C., to the streets of Berlin, the coast of Finland, and into the heart of Mother Russia herself before returning home for a final showdown with an enemy from America's past more sinister and deadly than has ever been seen before.--Back cover.
