Published in 2017, it's an interesting volume
- The author is Mormon, a historian, but really gets down to the unpleasant details.
- Heavily annotated, with an accessible bibliography (to check as needed).
If you're wanting to argue with Mormons, this book won't help you. It's more history, and the likely sources of both the texts, and much of the theology. It's quite up front, mirroring the LDS' own publishing of detailed historic documents (complete with various changes).
I got it wanting a better feel for John D Lee's confession, the connectivity to early restoration groups, Swedenborg, etc. The author draws from quite a bit ... even the Testaments of the Twelve (jewish).
Ben may wish to comment, yea or nea.
