Six Gun Snow White [EPUB ebook] 

A plain-spoken girl relates the history of her parents, a Nevada silver baron and his native-American wife, Gun That Sings. Her mother dies in childbirth, leaving her baby girl alone in a harsh world that offers no place for a half-native, half-white child. After being hidden for years, a very wicked stepmother finally gifts her the name Snow White, referring to the pale skin she will never have. Six-Gun Snow White is a fascinating and enchanting tale, at once familiar and entirely new.
