Reluctant hero, Honore Greenwood, has a knack for embroiling himself in the most violent conflicts of the Southern Plains. Known as Plenty Man to the Comanches, Honore serves as ransom negotiator for captives among the Indians. As if his life wasn't in danger enough, Honore has offered his services to the New Mexico Volunteers in the Civil War. But as Honore's luck would have it, he's in the same unit as Luther Sheffield, a man whose grudge against Greenwood knows no boundaries, even though they are fighting on the same side.
