Continuing the trilogy that began with A Blaze of Glory, New York Times bestselling author Jeff Shaara returns to chronicle another decisive chapter in America's long and bloody Civil War. In A Chain of Thunder, the action shifts to the fortress city of Vicksburg, Mississippi. There, in the vaunted "Gibraltar of the Confederacy", a siege for the ages will cement the reputation of one Union general and all but seal the fate of the rebel cause.
