My friend
Craig L. Foster, with Marianne T. Watson, just published a book which arrived
today (needless to say, it was read almost straight away) which I would like to
recommend:
American Polygamy: A History of Fundamentalist Mormon Faith (Charleston, S.C.: The History Press, 2019).
It is a very
good, fair overview of the origins and developments of, as well as debates
within the various Fundamentalist groups.
While I am not a fan of Lindsay Hansen Park, she did a good job interviewing both authors in her "Year of Polygamy" podcast:
Craig also co-edited, with Newell Bringhurst, another volume that also discussed
Fundamentalist Mormon groups that came out only a few years ago:
The Persistence of Polygamy, volume 3: FundamentalistMormon Polygamy from 1890 to the Present (John Whitmer Books, 2015)
Both volumes
gets my much-coveted two thumbs up:
