A Bright Shining Lie is a passionate and epic account of the Vietnam War, centering on Lieutenant Colonel John Paul Vann. His story illuminates America's failures and disillusionment in Southeast Asia. Vann, a field adviser to the army when US involvement was just beginning, quickly became appalled at the corruption of the South Vietnamese regime, their incompetence in fighting the Communists, and their brutal alienation of their own people.

Finding his superiors too blinded by political lies to understand that the war was being thrown away, Vann secretly briefed reporters on the true happenings. Among those reporters was Neil Sheehan, who became fascinated by Vann, befriended him, and followed his tragic and reckless career.

Sheehan recounts Vann's astonishing story in this intimate and intense meditation on a conflict that scarred the conscience of a nation. The narrative is an eloquent and disturbing portrait of a man who, in many ways, personified the US war effort in Vietnam, a soldier cast in the heroic mold, an American Lawrence of Arabia.
