The LDS Church currently teaches they have the fulness of the temple ordinances and all that God intended to reveal on the subject. Again, I totally disagree. The LDS Church did not previously believe or teach they had the fulness of the temple teachings. That is a recent claim and is simply not true.
If you love LDS history as I do, especially the Nauvoo era, you will love this book. Be prepared for a refreshing and unusual treatment of the subject. This is decidedly not a telling of the story of Mormon polygamy from the standard or traditional LDS point of view. The author takes advantage of RLDS sources that most LDS authors will dismiss. This book is a call to repentance, especially to those who still believe polygamy is ordained of God or was taught or practiced by Joseph Smith. If you are a descendant of a polygamous family, you must read this book. Your appreciation for Joseph will increase and your eyes will be opened about how polygamy really came about in Mormon history.
