Spies In Canaan by David Park

A retired man, once a young conscript working in military intelligence during the Vietnam War, receives a cryptic message that drags him back into the murky ethics and half-truths of his past. Haunted by the disappearance of a friend and by his own complicity in psychological operations and propaganda, he embarks on a journey to uncover what really happened. As memory, guilt, and contested histories collide, he searches for accountability and the possibility of redemption in the long shadow cast by war.
