During the Hours of Darkness; a book by Bill Lynch begins with the history of Vietnam built around fictional characters with their own fictional stories and adventures.

The book begins with how the Vietnam War began and details a history that began in 111 BC through the present day.

Hours of Darkness continues with its fictional character being involved in a very true battle of Hue City, Vietnam, in 1968 during the Tet holiday offense. This offense started attacks on over one hundred cities, towns, and military compounds across Vietnam.

The fiction story continues with the two main charters meeting and having to escape through a tunnel to avoid capture, murder, and rape.

The Hours of Darkness has three key details mentioned in its pages, which I want to bring to your attention.

The Cu Chi tunnels are real, and they are tourist attractions today.

The Vinh Moc tunnels are real, and they are also tourist attractions today.

The senseless killings of Vietnamese civilians, as well as the number of Americans, and Viet Cong soldiers killed during the battle of Hue, are also facts.
