Six-Gun Snow White

A retelling of "Snow White" set in the "gritty gun-slinging west." Her parents were a Nevada silver baron who forced the Crow people to give up one of their most beautiful daughters, Gun That Sings, in marriage to him; her mother's life ended as hers began. Our narrator, born into a world with no place for a half-native, half-white child, is hidden for years by a very wicked stepmother who gifts her with the name Snow White, referring to the pale skin she will never have. Now she's a gunslinger in West that's wilder than any you can evoke....
