On September 16, 2007, machine gun fire erupted in Baghdad's Nisour Square, leaving seventeen Iraqi civilians dead, among them women and children. The shooting spree, labeled "Baghdad's Bloody Sunday," was neither the work of Iraqi insurgents nor U.S. soldiers. The shooters were private forces working for the secretive mercenary company, Blackwater Worldwide.

This is the explosive story of a company that rose a decade ago from Moyock, North Carolina, to become one of the most powerful players in the "War on Terror." In his gripping bestseller, award-winning journalist Jeremy Scahill takes us from the bloodied streets of Iraq to hurricane-ravaged New Orleans to the chambers of power in Washington, to expose Blackwater as the frightening new face of the U.S. war machine.
