A prequel dealing with Sam Weston's parents.
"The CIA’s Clandestine Division has gone rogue. The conspiracy has its roots back in Vietnam, where a crack Special Forces team is sent to kill a North Vietnamese sniper, who is creating carnage with a devastating new weapon. An isolated US Fire Support Base is losing men by the hour. They are later on a covert patrol in hostile Laos, when a B52 bomber is downed by SAMs, and crashes into their laps. Tasked to rescue the aircrew, they come under missile attack from a rogue CIA plane. Their leader and all the aircrew perish.
After the war ends, the survivors, dedicated to seeing justice done, form a teamin the US to hunt down those who ordered the CIA air strike. What they discover is a CIA being used like an illegal, secret army, doing the bidding of a group of corrupt Washington politicians and their rich, powerbroker supporters. The odds are massively stacked against them succeeding. But they have amongst them a formidable ex Delta Force operator. She has a plan that no one could have imagined. But they also have a traitor in their midst too."
