New York Times bestselling author David Hagberg continues his successful Kirk McGarvey series in Tower Down, a searing thriller about terrorist attacks on NYC's pencil towers.

A freelance killer, code-named Al-Nassar, “the Eagle,” topples a New York City pencil tower and sends it crashing down onto the street. Hundreds of people are killed—both the multi-billionaires inside and the innocent bystanders on the sidewalks more than one thousand feet below. It's like 9/11 all over again.

CIA legend Kirk McGarvey believes that someone in the Saudi Arabian government is behind the attack. The internal pinch of sharply declining oil revenues and the escalating costs of defending its borders against ISIS have made the Kingdom desperate. The Saudis hope to force the US to return to the Mideast and destroy their enemies, including ISIS.

But no one in the White House or even in the CIA wants to believe that their loyal Saudi allies would do such a thing. Only McGarvey, his partner, who is also the woman he loves, and his long-time friend, the computer genius odd-duck Otto Rencke, accept the truth and understand that another attack on a Manhattan skyscraper is imminent.

Can they stop the terrorists in time?
