A true shocking story from the bestselling author of Everest and Into the Wild. The small town of American Fork, Utah, was rocked by the brutal murder of a 24-year-old woman and her daughter. The criminals were quickly caught, but they insisted that they received God's blessing for their actions. Why did the followers of the Mormon church commit this bloody crime? And what else does their faith call them to? This book takes us into the heart of the Mormon community, where 40,000 people still practice polygamy and avoid all contact with people of other religions.
