Tara Westover's memoir begins with scenes from her Mormon childhood in an isolated mountain valley in Idaho. The youngest of seven, she was home schooled by her mother, a midwife. Her father, obsessed with the End of Days, stockpiled food and ammunition and hid his children from the Feds. Her memoir charts how she broke free, educated herself and kept going, eventually making it to the Univeristy of Cambridge for a PhD in history. Now separated from her family, Tara Westover joins Kathryn to talk about how her journey has transformed her, and the pain of leaving her family behind.
