Harmon is a CIA/DEA enforcer investigating Arab terrorists captured in Mexico. With his team–seductive FBI agent Zara and spy-drone pilot Sharp–he flies to Istanbul and uncovers a brutal plot: Islamic extremists plan to use Sonora drug-smuggling routes to bring deadly weapons, and leaders, into the U.S. To prevent an attack on America, Harmon must turn these two savage forces against one another before his time–and his luck–run out.
