To stop a savage war from spreading west, two brothers stare down an army. The year is 1863. Even as the Union Army verges on total victory over the rebellious south, there are those in the North who clamor for a negotiated truce. Along a creek in the Indian Territories, North and South collide, and conflict simmers between slaveholding plantation owners and the settlers who would keep the West free. As this tension threatens to boil over into open war, hardened settler Ben McQueen goes east to plead for help from Washington. But when an assassin in Kansas City ambushes and nearly kills McQueen, his sons must try to fulfill the mission themselves. Though brothers, Jesse and Pacer Wolf McQueen have grown up in different worlds. But when a conspiracy threatens to destroy their family and tear apart the country they love so dearly, they will put aside their differences and fight. As long as these brothers stand together, the Union has a chance.
