I have rather mixed feelings about this book:
On the one hand this book is an academic book, and the author is definitely writing for and to anthropologists (with many references to anthropological thought and other anthropological works). Personally I'm not an anthropologist, and I have no intention of becoming one, so if you're like me you have to be willing to slog through some dry parts. There were whole sections of the book which I found largely unenlightened, something which I think most will find true.
However on the other hand this academic side is also one of the strong suits of the book, as it seriously examines the underpinnings of the Holy Spirit Mobile Forces (HSMF) and looks beyond the myths and flat out lies. This book was the first place I found a serious treatment of the subject (everywhere else Alice Lakwena seems to be dismissed as, quite literally, a crazy witch). It's very interesting to get the real story, and to get the insider's view as well.
My other complaint is that I rather disagree with her take on spiritual things. She is an anthropologist, and I would say also nonreligious, so she treats spiritual things as human and cultural constructs and nothing more. So while she has some interesting insights to share, and she does write an interesting and helpful history of Acholi and Christian thought in Uganda, I largely distrust the conclusions she reaches on spiritual matters.
So the book is good. It has some definite insights into the HSMF, and is the only book I have come across which treats them seriously and takes the time to try and understand them. It really opened my eyes, because I think most assessments of the HSMF get it completely wrong. But it's also a bit of a hard read at time, and requires quite a bit of sifting to get the interesting insights from the academic verbiage. Definitely only for someone with a real interest in Uganda -- and Ugandan history at that. This is not a good book to read if you're interested in learning about the Lord's Resistance Army (LRA). They're mentioned at times, but the sections on the LRA are dated and incomplete.
