November begins: Looking for natives

As the new month begins and librarians everywhere take down their Day of the Dead and Halloween displays, we are putting up a display of Native American books, authors and posters about tribes. I find it sad that I have so few books by acknowledged Natives and wonder if anyone knows some authors or works that I should put on my library wish list for when our phantom funding becomes reality? I have Joseph Bruchac, Sherman Alexie, and Russell Freedman, but am looking for more sources to celebrate this rich heritage.
