A multilayered, bone-chilling narrative of messianic delusion, savage violence, polygamy, and unyielding faith. This is vintage Krakauer, an utterly compelling work of nonfiction that illuminates an otherwise confounding realm of human behavior.

Jon Krakauer’s literary reputation rests on insightful chronicles of lives conducted at the outer limits. In Under The Banner of Heaven: A Story of Violent Faith, he shifts his focus from extremes of physical adventure to extremes of religious belief within our own borders. At the core of his book is an appalling double murder committed by two Mormon Fundamentalist brothers, Ron and Dan Lafferty, who insist they received a revelation from God commanding them to kill their blameless victims. Beginning with a meticulously researched account of this "divinely inspired" crime, Krakauer constructs a multilayered, bone-chilling narrative of messianic delusion, savage violence, polygamy, and unyielding faith. Along the way, he uncovers a shadowy offshoot of America’s fastest-growing religion, and raises provocative questions about the nature of religious belief.
