The War Criminal's Son brings to life hidden aspects of the Civil War through the sweeping saga of the firstborn son in the infamous Confederate Winder family who shattered family ties to stand with the Union.

General John H. Winder was the commandant of most prison camps in the Confederacy, including Andersonville. When Winder gave his son William Andrew Winder the order to come south and fight, desert, or commit suicide, William went to the White House and swore his allegiance to President Lincoln and the Union. Despite his pleas to remain at the front, it was not enough. Winder was ordered to command Alcatraz, a fortress that became a Civil War prison where he treated his prisoners humanely despite repeated accusations of disloyalty and treason because the Winder name had become shorthand for brutality during an already brutal war.

John Winder died before he could be brought to justice as a war criminal. Haunted by his father's villainy, William went into a self-imposed exile for 20 years and eventually ended up at the Rosebud Reservation in South Dakota to fulfill his longstanding desire to better the lot of Native Americans.

In The War Criminal's Son, Jane Singer evokes the universal themes of loyalty, shame, and redemption in the face of unspeakable cruelty.
