Under the Banner of Heaven: A Story of Violent Faith - Jon Krakauer There's nothing in this book that is untrue, per se. However, Krakauer has a particular story he wants to tell, and so drastically oversimplifies complex historical and cultural phenomena, and draws causal conclusions that are, at best, facile. There's a certain aspect of breathless exposé here that obscures the complexity of a minority, counter-cultural religion and its history. If you want a good history of Mormonism and/or introduction to Mormon culture and society, there are better (albeit probably less entertaining) choices.
