It’s 1863. America’s most legendary war leaders arrange a meeting ―a clandestine alliance that will never show up in any history book. Their mission: To heal a war-torn nation by bringing the remnants of a prized ship back to U.S. soil―one that may lie on a mountaintop inside the Ottoman Empire, where the men who seek it are only days away from killing one another. The battles will rage at sea and upon land―with enemies both past and future. Colonel John Henry Thomas of the Union Army will come face to face with his mortal enemies in the South and a dark entity that has been trapped on top of God’s Mountain for a millennium.
