My wife and I were both LDS members, and in combination with what we were taught at church and temple services, Origins of Power sheds invaluable light onto the way the church operated in its beginning and how it operates today. Quinn's research and dedication to factual evidence (I've followed through on many of his sources), is no less than exciting and complete. I note that Quinn was excommunicated from the church, because of the sensitive, "unauthorized" information he (and many other authors) have brought forth concerning the origins of Mormon religious beliefs and practices. As a historical researcher, and once fond member of the church, I highly recommend Quinn's work to anyone interested in Mormon history, and who are fair minded and strong willed.
