In the war-ravaged borderlands of Ukraine, a Russian mercenary unit has gone rogue. Its members are the most criminally violent, psychologically dangerous combatants to ever set foot upon the modern battlefield. As they move from village to village, committing horrific war crimes, they meet little resistance as all able-bodied men are off fighting the war. Simultaneously, a team of Russian soldiers has been dispatched by the Kremlin to loot truckloads of art and priceless cultural treasures hidden away in a host of churches, museums and private homes. When multiple American aid workers are killed, America’s top spy is sent in to settle the score. But in a country so vast, will Scot Harvath be able to find the men in question and, more importantly, stop them before they can kill again?
