Sootface, Paperback/Robert D. San Souci

Once, an Ojibwa man whose wife had died raised three daughters alone. The two older girls were lazy and bad-tempered, and made their youngest sister do all the work. When the flames from the cooking fire singed her hair or burned her skin, they laughed and called her Sootface. While she worked, Sootface dreamed that one day she would find a husband. Then a mighty warrior with the power to make himself invisible decides to marry. Only a woman with a kind and honest heart could see him, and be his bride. Though her sisters ridicule her, Sootface sets off to try her luck, never looking back. Her courage and good nature bring her the husband she has longed for.
