Purgatory : A novel of the civil war

During the Civil War, two young soldiers on opposite sides find themselves drawn together. One is a war-weary but scholarly Southerner who has seen too much bloodshed, especially the tortures inflicted upon the enemy by his vicious commanding officer, his uncle. The other is a Herculean Yankee captured by the rag-tag Confederate band and forced to become a martyr for all the sins of General Sheridan's fires. When these two find themselves admiring more than one another's spirit and demeanor, when passions erupt between captor and captive, will this new romance survive the arduous trek to Purgatory Mountain?
