Brandon Condley survived five years of combat in Vietnam as a marine only to lose the woman he loved to an enemy assassin. Now he is back, and working to recover the remains of unknown American soldiers. On a routine mission, Condley finds a body that doesn't match its dog tags - a body that propels him into a vortex of violence and intrigue where past and present become one. As the mystery of the dead man unravels, a link is revealed to two notorious assassins, 'Salt and Pepper', who led a deadly Viet Cong ambush against Condley's own men. Galvanized by a fresh trail to these long-lost deserters, Condley has finally found a purpose: under the auspices of his government job, he is going to hunt down the traitors. On his own, he is going to kill them. Condley's hunt cannot be kept secret from his former enemies, or his friends. And in the shadows that linger from Vietnam's long season of darkness and terror, he has no way of knowing which side is more dangerous.
