From Barnes & Noble Review:

"In bestselling wilderness adventures like Into Thin Air and Into the Wild, award-winning journalist Jon Krakauer has taken us to the extremes of human experience. Now he focuses his sights on extremism of another sort in Under the Banner of Heaven, a chilling tale of violence and fanaticism that strikes at the very heart of religious faith in America.

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."
