Lost Soldiers by James Webb

Decades after the Vietnam War, Brandon Condley tracks down missing U.S. soldiers believed to be alive deep in Southeast Asia. His search uncovers black-market arms rings, old wartime betrayals, and a secret list of names the government doesn’t want surfaced. Condley’s nemesis, a ruthless Vietnamese officer, returns with a vendetta that ignites the final act. The emotional punch lands when Condley confronts a soldier who never wanted to be found — forcing him to question loyalty, memory, and the price of war.
