# 1 AMAZON BESTSELLING MEDICAL THRILLER   Red Sparrow meets Inferno in Matt Miksa's debut which electrifies a Cold War spirit with fresh, modern-day expertise as our heroes wrestle society's darkest nightmares. In a far-flung Tibetan village, prayer flags flap against whitewashed houses and a majestic monastery stretches to heaven. It's Shangri-La--the earthly paradise--until a stranger staggers out of the forest and collapses into a bloody, lifeless mass. He's the first victim of a crippling epidemic, but he's no ordinary man. Olen Grave, an American intelligence officer, heads directly into the hot zone to investigate. Posing as a journalist, he joins the Chinese research team, led by a headstrong female virus hunter, Dr. Zhou Weilin. Together, the unlikely allies discover that Patient Zero was a spy who deliberately infected himself. But why? Who did he work for? As Olen and Dr. Zhou rush to uncover the shocking truth behind the epidemic, they unravel a twisted conspiracy that reaches from Beijing's great halls to Washington's corridors of power. With the superpowers now at the brink of war, the fate of the world will rest on the duo's shoulders.
