Under the Banner of Heaven

The Barnes & Noble Review - The centerpiece of the story is a grisly double murder committed in 1984 by Ron and Dan Lafferty, Mormon fundamentalist brothers who claimed to have killed at God's direct command. In Krakauer's expert hands, the bizarre details of this brutal crime play out against the equally bizarre history of the Church of Jesus Christ of Latter-day Saints (LDS) and its subsequent splintering into fundamentalist sects over the issue of polygamy -- a sacred doctrine put forth by Mormon founder Joseph Smith in 1830.
