A Jack Sigler Thriller

When a raid on an insurgent safehouse reveals a clue to decoding the world's most mysterious manuscript—and possibly a recipe for creating the ultimate weapon of mass destruction—Delta operator Jack Sigler must forge a new black ops team to avert catastrophe, a team of deadly warriors with dangerous secrets—the Chess Team.

When the president of the United States falls victim to a weaponized and contagious strain of the disease, the Chess Team - King, Queen, Rook, Knight, and Bishop - are assigned to protect Sara Fogg, a CDC detective, as she journeys to the source of the new strain: the Annamite Mountains in Vietnam.

When a death in the family pulls King away, and the rest of the team is sent on a mission, Fort Bragg is attacked by a strange and overwhelming force. When the dust settles, Fiona is gone. The attack is part of a larger offensive. Around the world, the last speakers of ancient languages are being systematically exterminated. As they fight to find the mastermind behind the killings and Fiona's kidnapping, the team is hunted by strange creatures that defy explanation.
