Big Red, whose given name is Horatio Coonrod, is a teenaged boy in September 1864, the waning months of the War Between the States, in this historical novel that combines fictional characters and actual historical events and persons. He lives in the Florida Panhandle, in Jackson County, just east of Marianna, the county seat, as does his betrothed, Sue McKinnie. The times are desperate for the Confederacy but more so for Jackson County and the surrounding area, with a large force of battle-hardened Union veterans converging on Marianna. The Southern town is defended only by a few Confederate regulars, walking wounded, and citizens who make up a Home Guard, ranging in age from thirteen years to seventy-eight-a force half the size of the Union cavalry. The battle goes badly for the Southerners. Red was wounded, captured, and taken to the war's most infamous Union prisoner of war camp in Elmira, New York, but he is protected and guided by the hand of the Lord as he makes his way back to his home, family, and the only girl he's ever loved. He must then engage again in deadly combat in an attempt to regain what has been forcibly taken from him.

Red is transformed by the devastating trials he endures on his 1,100-mile journey home. He realizes the unfortunate transformation he went through and his need to seek the redemptive grace the Lord makes available to those who seek it. Sue McKinnie also struggles during this time, not knowing whether her beloved is alive or not. She clings to hope when it seems there is none. Her trials are recounted, illustrating how the Lord buttresses her against utter hopelessness through her extremely strong and devout faith. Together, their story is a tale of hope, faith, and love triumphant.
