A deadly fall on a rugged stretch of California coast. A burglary gone wrong in Virginia. These incidents seem unrelated, but the victims were living undercover, their true identities closely held secrets. They are members of a classified team, the last line of defense against foreign threats. Now, someone is assassinating them, one by one, taking out family members and innocent bystanders to make the deaths seem like accidents. Captain John Hayes, a special operations legend, has left the military to settle down with his family. But when he pieces together a pattern behind the murders and discovers that his protÔegÔee Claire Rhodes, a brilliant assassin, is the prime suspect, he returns to duty to unmask the attackers. With every success, the killers grow bolder. Their ultimate goal: Lure Hayes and his remaining fellow soldiers to Manhattan, to eliminate them all in a single devastating strike. To save his teammates and thousands of innocent lives, Hayes must find a way to stop a seemingly unstoppable weapon.
