Radiant Angel (John Corey #7) by Nelson DeMille

After a showdown with the notorious Yemeni terrorist known as The Panther, John Corey has left the Anti-Terrorist Task Force and returned home to New York City, taking a job with the Diplomatic Surveillance Group.

Although Corey's new assignment with the DSG - surveilling Russian diplomats working at the U.N. Mission - is thought to be "a quiet end," he is more than happy to be out from under the thumb of the FBI and free from the bureaucracy of office life.

But Corey realizes something the U.S. government doesn't: The all-too-real threat of a newly resurgent Russia.

Prescient and chilling. DeMille's new novel takes us into the heart of a new Cold War with a clock-ticking plot that has Manhattan in its crosshairs.
