Born and raised in Sioux country, Katie McCabe, daughter of an Indian trader, finds herself alone and adrift after her family is killed in a battle between the Indians and the soldiers. Black Moon, the fierce Oglala warrior who has sworn to fight to keep the white people from taking his land, rescues her and brings her to live in his village. The love that ignites between these two wild hearts is tested by Katie’s obligation to marry a man she does not love, by a promise made to a dying woman, the treachery of a jealous adversary, abduction by Crow Indians, the love of a cavalry lieutenant, and the tensions that erupt between the Sioux and the U.S. Army during the tumultuous 1850s, as a headstrong white girl and a proud Oglala warrior fight for their love and the wild country of their birth.
