Here's the story in a nutshell: Claire Sanchez, who witnessed her mother's murder twenty years ago, is now a natural therapist for a church run psychiatric hospital. She uses tea, massage, and a certain amount of woo to help the patients. When one of her patients runs off into the desert around the hospital and is later found dead, Claire decided to investigate the local archbishop because he made her medicine woman spidey senses tingle. DeBlassie also gives us that archibishop's perspective and there's no doubt that Anarch is the murderer. DeBlassie also makes it clear that Anarch is possessed by something malevolent. The archbishop plays a cat and mouse game with Claire because, not only does he want to kill her for investigating the murder, he wants to kill her because he has a vendetta against medicine women.
I'm not exactly sure why I kept reading this book, other than to say I was hooked by the setting. When so many of the nouns have multiple adjectives, you can't help but see the scene laid out for you. DeBlassie set up an interesting battle between native good and imported evil. Some readers might enjoy this, but I don't think many people are going to get into this book.
