"A smart, sleek, and absolutely gripping thriller that swept me away." - Brad Thor

"David McCloskey has delivered another mesmerizing tale of intrigue to follow the incredible Damascus Station. Moscow X is even better; an utterly authentic and deeply compelling thriller that is among the very best espionage fiction in print." - Mark Greaney, #1 New York Times best-selling author of The Chaos Agent: A Gray Man Novel

"A spellbinding journey into the brutal, shadowy intrigues of the Russian elite and the underground world of espionage. The Russian condition, as seen through Anna’s eyes, is both moving and terrifying. An electrifying read. I could not put it down." - Clarissa Ward, CNN chief international correspondent and author of On All Fronts

"Moscow X brilliantly captures the nuances of field work in hostile environments, the thrill and terror that grip every intelligence officer when they are in the belly of the beast. McCloskey is the new poet laureate of the CIA operations officer." - Marc E. Polymeropoulos, former CIA senior operations officer and author of Clarity in Crisis

"There is a new generation of spy novelists storming the genre, and David McCloskey must be counted as one of the best. Moscow X is a white-knuckled, fast-paced journey into the modern age of spy craft, where high-tech espionage jostles dangerously against old school cunning and Machiavellian intrigue; and where men and women risk everything to uncover an elusive and, ultimately, lethal truth." - Kathleen Kent, New York Times best-selling author of Black Wolf

"Moscow X is a propulsive thrill ride and a moving portrait of life, betrayal, and vengeance in Putin’s Russia. Those of us who spent our careers running spies have been waiting for the next John le Carré, Charles McCarry, or Jason Matthews—authors who told riveting and deeply authentic stories about intelligence wars fought in the shadows. With Moscow X, David McCloskey takes his place among that company." - John Sipher, former CIA senior operations officer

"A breathless intrigue limned with elegance and grace…David McCloskey has asserted himself as a world-class thriller writer. With only two novels to his name, he already calls to mind le Carré, Forsyth, and Silva." - Gregg Hurwitz, New York Times best-selling author of the Orphan X series
