When a body with Russian military tattoos is found floating in a lake outside Berlin, the CIA immediately takes notice. And the murder coincides with the defection of one of the CIA's upper-level officers. Alden Maines crosses the Rubicon and decides to cash in as a double agent for Russia. But Arkady Lavrov of Russia's intelligence service (GRU) has other plans. He immediately announces Maines's defection to the world and then pumps him for every last ounce of intel. Analyst Jonathan Burke and agent Kyra Stryker are up against their most formidable enemy yet, and their lives and the fate of America's most important assets in the New Cold War hang in the balance.
