The Mystery Healer of Smoky Mountain

Who is the mystery healer concealed in the Great Smokey Mountains of East Tennessee? Why does he need to keep his identity a secret?
Marni Granger is a young woman who lives at the base of the mountain. As a child, falling against a hot cooking pot, she burns the side of her face. Being teased at school and later stared at as an adult, Marni remains living in isolation with her grandfather. Her one friend is a half wolf dog, rescued by her as a pup.
Marni would like a life similar to other young women, yet she feels all this will be denied her due to her facial deformity.
Heading off to the base of the mountains to pick berries, she wanders up and becomes lost in the dark. When her pet disappears, Marni is terrified and cries out to the Lord for help. A mysterious woman in white calls her name then leads her to a large cabin on the plateau.
Here she will meet a handsome man and the hidden surgeon who performs reconstruction operations, unallowed in 1885.
