A freelance killer, code-named Al-Nassar, “the Eagle,” blows the supports on a pencil tower in Manhattan and sends it crashing down. Hundreds of people are killed, both the multi-billionaires inside and the innocent bystanders on the street more than one thousand feet below. It's like 9/11 all over again, only this time, no airplanes are involved.

Retired CIA assassin Kirk McGarvey believes that someone in the Saudi Arabian government, feeling the internal pinch of sharply declining oil revenues and the escalating costs in money and manpower of defending its borders against ISIS, is behind the attack. The Saudis hope to awaken America's will and military might against ISIS.

But no one in the White House or even in the CIA wants to believe that more Americans are going to die. Only McGarvey, his partner Pete Boylan, and his long time friend, the computer genius odd-duck Otto Rencke, believe that another attack on a Manhattan skyscraper is imminent.

The trio embarks on a mission to find the Eagle and stop him before he strikes again. They’re hot on his trail—but the clock is ticking.
