Armed with two pistols and a dagger, Sarah Jenkins Boudreaux, a very dark black woman, boards the side paddle wheeler "Ida" and goes south to find her husband, a tall, white apprentice printer and former Union sailor. A terrifying telegram has come; he is missing in a war without mercy. "I am coming for you," she writes. "I have two pistols and a dagger. I love you, and I am coming for you." With those words, Sarah goes into the slave-holding Confederacy, the heart of darkness. Guarded by a crew of American sailors and Marines, she goes upriver on the steam launch "The 13." She will find him. Nothing will stop her. In this cold, wet December of 1864, the demons of war lurk on the Savannah River. This is Sarah’s story.
