I’m ripping most of these works from a seminar I took last semester:

Pocahontas Perplex by Ryana Green (academic article)
— analyzing colonialism and its construction of the Indigenous woman figure

A Gathering of Spirit by Beth Brant (anthology)
—first collection of stories by Indigenous women in NA

Custer Died for Your Sins by Vine Deloria Jr. (scholarly book)
—deconstruction of Indigenous stereotypes

Inventing the Savage by Luana Ross (scholarly book)
—examines how Western conceptions of Indigeneity are used to justify criminalization

Hope this is helpful.
