Compared to the documentary film (Breaking Habits) released in theaters in 2019, this is a more personal and in-depth look at the life of Sister Kate, prior to forming the Sisterhood, Where the film-makers focused more on the central valley of California, The Accidental Nun is an autobiography written by Sister Kate in 2014, just before the founding of the Sisterhood and reveals the stories and experiences that led her to founding the new-age Order of nuns. Sister Kate and Sister Rosa worked together to complete this book over the early years of the Sisterhood.

The tearful and witty story begins as a suburban mother of three is unpacking the family's belongings after returning from nearly a decade in Europe, and stumbles across secrets kept by her husband. Clues and secrets that she begins to put together in boxes, that she protects with her life. This is the sadly common story of a patriarchal victimization of women, and the hardship one woman had to overcome to rise above it all and ultimately gain world-fame with her anarchist, activist order of nuns. This is the story of a Beguine-revivalist movement. This is the story of the rise and return of St. Hildegard de Bingen. This story represents one of many of the women who are performing the role of midwives who, while giving birth to a newborn matriarchy, also wield a whip to gently tame the patriarchy.
