In early 1990, in response to apocalyptic prophecies given by her mother, Elizabeth Clare Prophet, Erin Prophet entered a network of underground bunkers in Montana along with members of her mother's Church Universal and Triumphant, a controversial New Age sect. Emerging to find the world still intact, Erin was forced into a radical reassessment of her life and her beliefs. She had spent her adolescence watching her mother vilified as a dangerous cult leader even while attempting to meet her expectations by becoming a "prophet" herself.

Prophet's Daughter describes Erin's search for her mother's origins and motivations. With the craft of a storyteller, she describes the combination of health crises and external pressure that drove her mother's ever-more dire prophecies. She reveals how the allure of infallibility led her mother to a conspicuous downfall, and how her mother's rapidly progressing Alzheimer's disease truncated any hope of resolution. A remarkable memoir with implications for the dialog about power, group behavior and the future of religion.
