Denton employs the 2019 murder of several young wives and mothers from the sister Mormon communities of La Mora and LeBaron as a point of departure to examine the tumultuous history of the Church of Jesus Christ of Latter-day Saints in the U.S. and along the border...But this is more than a modern true-crime story, as Denton reaches back into the history of Mormonism and finds a deep well of violence, including the Cain-and-Abel rivalry and 'blood atonement' murders involving Joel and Ervil LeBaron from the 1970s to the 1990s and the Mountain Meadows Massacre of 1847, when a Mormon militant group murdered a traveling party of 140 innocent immigrants and then tried to cover it up, 'the worst butchery of white people by other whites in the entire colonization of America'...Denton also dissects other elements of the Mormon practice, including legacies of male superiority, female servitude, and forced polygamy...Thorough research and balanced reporting combine in a riveting investigation..
