Reddit mentions of Navaho Witchcraft

IIRC, there was a woman in this sub a while back that said she married a Navajo and went to live on the res with him and she was given two copies of this book by some other people there. It's an interesting read.

These are all good books on the topic, and cover it effectively to some degree. The most famous book is probably the examination of Skinwalker Ranch which just takes it's name from the creature, and which doesn't necessarily explore the creature by itself too deeply.
