In the Approaching Fury: Voices of the Storm 1820-1861, biographer and historian Stephen B. Oates tells the story of the coming of the American Civil War through the voices and from the viewpoints of thirteen principal players in the drama, from Thomas Jefferson and Henry Clay in the Missouri crisis of 1820 down to Stephen A. Douglas, Jefferson Davis, and Abraham Lincoln in the final crisis of 1861.

This unique approach shows the crucial role that perception of events played in the sectional hostilities that bore the United States irreversibly toward a national smashup.

In addition to Jefferson, Clay, Douglas, Davis and Lincoln, other speakers and participants are Nat Turner, William Lloyd Garrison, John C. Calhoun, Frederick Douglass, Harriet Beecher Stowe, George Fitzhugh, John Brown, and Mary Boykin Chesnut. Each character takes his or her turn onstage, serving as narrator for critical events in which he or she was the major instigator and participant or eyewitness.

In writing the dramatic monologues, Oates drew on the actual words of his speaker - their letter, speeches, interviews, recollection, and other recorded utterances - and then simulated how, if they were reminiscing aloud, they would describe the crucial events in which they were the principal actors or witnesses. All the events and themes in the monologues adhere to the actual historical record.
