Despite decades of treaties, military missions, and covert actions devoted to preventing it, Iran has finally assembled its first nuclear bomb and the U.S., with UN backing, has decided it's time to take direct action. The first move is to blockade the Persian Gulf with a carrier strike group, but Iran strikes back quickly. With Russia's backing, Iran launches a devastating attack and now the U.S. forces are in a race against the clock to survive until reinforcements arrive and a counter-strike launched. While events grow desperate in the Middle East, a plot to kill the President is unfolding. Jake Harrison, a now AWOL Navy SEAL, is lured back into action by his former partner Christine O'Connor to find and stop the freelance assassin, a man who has long been Harrison's nemesis. With a deadly war brewing on two fronts-both overt and covert-the uneasy allies of Jake and Christine must use all their resources to circumvent the coming war. And as tensions threaten to boil over, Jake will be faced with the ultimate question: what is he willing to sacrifice for the revenge he wants?
