The Ones They Left Behind is a sweeping, riveting, historically accurate account of post-Civil War America told through the journey of Harriman Hickenlooper, a Union veteran who sets off on a one-man peace march to heal the wounds of a bitter and divided country by retracing his steps on Sherman s March to the Sea. This time, instead of carrying a gun, he will carry a flag. Instead of marching for war, he will march for peace and find a reason to live and love again.
