In Good Faith is the first of a two-volume, accessible narrative history of America's involvement in Indochina, from the end of World War II to the Fall of Saigon in 1975. The books chart the course of America's engagement with the region, from its initially hesitant support for French Indochina through the advisory missions following the 1954 Geneva Accords, then on to the covert war promoted in the Kennedy years, the escalation to total war in the Johnson era, and finally to the liquidation of the American war under Nixon.

Drawing on the latest research, unavailable to the authors of the classic Vietnam histories, In Good Faith tells the story from the Japanese surrender in 1945 through America's involvement in the French Indochina War and the initial advisory missions that followed. It describes how these missions gradually grew in both scope and scale, and how America became ever more committed to the region, especially following the Gulf of Tonkin incident in 1964, which led to the first bombing missions over North Vietnam. It finishes at the climax of one of those operations, Rolling Thunder, and just prior to the first commitment of US ground forces to the war in Vietnam in the spring of 1965. Examining in depth both the events and the key figures of the conflict, this is a definitive new history of American engagement in Vietnam.
