From the back cover:
Half-breed Gabe Beaumont had had to choose between the Sioux tribe of his mother and the white family of his father, and his choice had cost him everything. Settlers had murdered his Indian wife and child, and now revenge was all he lived for. Riding westward with a renegade Sioux band, he became Tall Bear, a warrior with a wounded sould, a man with an anger and grief that tore away his gentleness and dreams-until a raid on a Wyoming stagecoach station brought him face-to-face with a feisty, red-haired beauty who would change his life...
Faith Kelly had run from her strict, pious upbringing toward the freedom of the frontier and a reckless husband. All too quickly, tragedy left her alone with an infant son and shattered plans. But Faith had drawn strength from the soaring hills, and her tough-minded courage flared when Indians attacked the stage stop that had become her home. She never guessed that Gabe Beaumont, the handsome, dark-haired cowboy who later rode into the station, was the Sioux warrior who had led that raid. He had changed worlds to claim the woman who was his destiny-and to fight for her love against the shadows and the danger that lurked in his wild heart.
