A DOJ counterintelligence lawyer pursues a Russian spy ring embedded at the heart of the American government. As deputy assistant attorney general for counterintelligence in the DOJ's National Security Division, Robert Cooper has built a storied career distinguished by high-profile arrests and prosecutions of enemy spies. One morning, he's approached by a Russian sleeper agent looking to defect. The agent offers Cooper alarming information: Russian operatives have infiltrated the US government at its highest levels, including a mole in the senior ranks of the FBI. Cooper's investigations lead to the discovery of a clandestine Russian plot--code named Operation Viper--involving deep-cover agents in senior government positions. As Cooper and his team at the DOJ race to uncover the Kremlin's plans and smoke out the traitors, a coup in Russia brings to power a militant extremist regime seemingly intent on sidelining the US on the world stage while Russia retakes its former Soviet territories. In Robert B. McCaw's fast-paced novel, high-stakes political intrigue mixes with riveting moments of international espionage.
