NOW A MAJOR TV SERIES STARRING ANDREW GARFIELD True crime in the American heartland. Under the Banner of Heaven is a riveting account of Mormon fundamentalism and renegade prophets, from the bestselling author of Into the Wild and Into Thin Air. Brothers Ron and Dan Lafferty insist they were commanded to kill by God. In Under the Banner of Heaven, Jon Krakauer's investigation is a meticulously researched, bone-chilling narrative of polygamy, savage violence and unyielding faith. An incisive look inside isolated Mormon Fundamentalist communities in America, this gripping work of non-fiction illuminates an otherwise confounding realm of human behaviour. PRAISE FOR UNDER THE BANNER OF HEAVEN 'A provocative look at the twisted roots of American fundamentalism.' Will Self, Evening Standard 'Books of the Year' 'Excellent . . . a lucid, judicious, even sympathetic account not just of Mormon Fundamentalism but of the seductive power of fanaticism in general.' Daily Telegraph 'Remarkable . . . for anyone interested in the wilder frontiers of spiritual conviction, this book is a must.' Independent 'Powerfully illuminating. . . . Almost every section of the book is fascinating in its own right, and together the chapters make a rich picture. . . . An arresting portrait of depravity.' New York Times Book Review ' Illuminating . . . provocative. . . . Krakauer is an adept chronicler of extremists [and] the tour guide of choice for secular quests.' Los Angeles Times Book Review
