Fifteen years after the events of the Natchez Burning trilogy, Penn Cage is alone. Nearly all his loved ones are dead, his old allies gone, and he carries a mortal secret that separates him from the world. But Penn's exile comes to an end when a brawl at a Mississippi rap festival triggers a bloody mass shooting, one that nearly takes the life of his daughter Annie. As the stunned cities of Natchez and Bienville reel, antebellum plantation homes continue to burn and the deadly attacks are claimed by a Black radical group as historic acts of justice. Panic sweeps through the tourist communities, driving them inexorably toward a race war.
