When the President of the United States falls victim to a weaponized and contagious strain of a genetic disease―one that kills its victims without warning or symptom―Special Forces commander Jack ‘King’ Sigler is on the case. He and his team of highly trained operators have been assigned to protect a CDC detective as she journeys to the source of the new strain: Vietnam’s Annamite Mountains. Surrounded by old landmines, harsh jungle terrain, and more than one military force not happy about the return of American boots to the Ho Chi Minh Trail, the fight for survival becomes a grueling battle. Pursued by VPLA Death Volunteers, Vietnam’s Special Forces unit, the team’s flight through a maze of archaic ruins reveals an ancient secret that may stop the disease from sweeping the globe―even as it threatens both the mission and their lives… International bestselling author Jeremy Robinson pulls no punches in his second installment of the Jack Sigler / Chess Team series, combining adrenaline-rush action with smart science, ancient legends, and stunning locations.
