I am reading a book by a non-native woman who was welcomed into the tribal sweat lodge and pipe smokeing ceremonies (or sermonies as she calls them) This was written in the early 70's.

Recently i read one (by Diane Smith?) about a woman who was a botanist in Yellowstone in the 1880's. Letters From Yellowstone is almost entirely comprised of postal communications between the characters.

I am also reading about Sarah Winnemucca, daughter of a tribal chief
who travelled to Washington to speak for her people.

Oh yes and a story about Belle Starr...
