Mystic Warriors (Mystic Dreamers, Band 3)

The white buffalo is a sacred and holy creature to the Lakota. Buffalo Dreamer, a holy woman, and her husband, Rising Eagle, have not only been blessed to see the white buffalo, they have eaten of its heart and have been told by the sacred beast that as long as the Lakota have the white buffalo hide, all will be well.
But all is not well. White hunters have stolen the sacred white robe and great misfortune has befallen the Lakota. Settlers continue to invade Lakota territory, backed by vicious cavalry forces that massacre women and children. The Lakota are starving and their anger is growing.
Led by Rising Eagle, a great force of Lakota and other tribes wage war upon the white man. Together they battle to regain the land stolen from them, to protect the precious buffalo the white man wantonly destroys, and to search for the sacred white robe.
