What to read after Black Elk Speaks?

"Black Elk Speaks is the story of the Lakota visionary and healer Nicholas Black Elk (1863-1950) and his people during the momentous twilight years of the nineteenth century. Black Elk met the distinguished poet, writer, and critic John G. Neihardt (1881-1973) in 1930 on the Pine Ridge Reservation in South Dakota and chose Neihardt to tell his story. Neihardt understood and conveyed Black Elk's experiences in this powerful and inspirational message for all humankind." "This new edition features two additional essays by John G. Neihardt that further illuminate his experience with Black Elk; an essay by Alexis Petri, great-granddaughter of John G. Neihardt, that celebrates Neihardt's remarkable accomplishments; and a look at the legacy of the special relationship between Neihardt and Black Elk, written by Lori Utecht, editor of Knowledge and Opinion: Essays and Literary Criticism of John G. Neihardt."--BOOK JACKET.
