In the war-ravaged borderlands of Ukraine, a Russian mercenary unit has gone rogue. Its members, conscripted from the worst prisons and mental asylums across Russia, are the most criminally violent, psychologically dangerous combatants to ever set foot upon the modern battlefield.
With all attention focused on the front lines, they have pushed deeper into the interior to wage a campaign of unspeakable barbarity. As they move from village to village, committing horrific war crimes, they meet little resistance because 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, Scot Harvath, is sent in to settle the score. But in a country so vast, will Harvath be able to find the men in question, and, more important, will he be able to stop them before they can kill again?
