Long ago, the legendary trapper known as Preacher took shelter with the Absaroka, and fell in love with a girl called Bird in the Tree. Twenty years later, he rescues a woman and her son from an ambush by the hated Blackfoot. The woman is Birdie, and the valiant young warrior is Hawk That Soars -- Preacher's son. Now the greatest fighter on the frontier is about to go to war, to protect a family he never knew he had. Hopelessly outnumbered by vicious warriors, Preacher and his son launch a war that will stain the Rocky Mountain snow with Blackfoot blood.
