Praised by Harlan Coben as "a fresh new voice" in crime fiction, ex-FBI agent Gene Riehl takes readers into a secret, high-stakes world of counterintelligence and espionage in his 2nd suspense-packed Puller Monk thriller FBI agent Puller Monk has been called in to track down a Leonardo da Vinci masterpiece that was recently stolen from a private collector in Washington, DC. But the culprit isn't an ordinary thief; she's a sleeper terrorist-an American who was abducted as an infant, renamed Sung Kim by her North Korean captors, and trained in the deadliest of arts. The National Security Agency (NSA) wants Monk to catch her before she carries out her next diabolical mission. Working so deep undercover that even the FBI and Monk's girlfriend are kept in the dark, the rogue agent plunges into a game of cat and mouse that could cost him his life-and the lives of many others. But Monk never backs off from a case, and he has his own unorthodox methods of getting the job done. As he moves within the shadows, Monk becomes both hunter and prey in an endgame more chilling than anyone could imagine.
