The opening of Westover's memoir features bravura nature description of the Idaho wild wheat dancing like a corps de ballet. This establishes that Westover intends to play the painful psychological insights from her searing family memoir against the stark landscapes she roamed unfettered in her strange Idaho childhood. Pater familias is a religious paranoid schizophrenic prepping for the end of the world and determined to eliminate the evil secular government from every aspect of daily life. Westover portrays the idiosyncratic beliefs and conspiracy theories that ruled her family matter-of-factly, as if every extreme Mormon were just the folks next door. Her father and mother divide the world into a simple binary of Godly and Satanic, and bury fuel and stock preserves so the family can survive the Days of Abomination which are sure to follow the collapse of the Satanic World after Y2K.
Mom is a midwife, so she can save many local women from the evil intentions of hospital birthing. She gathers herbs and brews patent medicines that eventually become the basis of family prosperity. While the older kids attended some school, Tara Westover is born in the era when no schooling at all was allowed by her grim father. Influenced by the Weaver killings in Montana and the Waco deaths in a Federal attack on the David Koresh religious enclave in Texas, fear of the overwhelming force and malevolence of federal government is a daily concern. The author does not mock her father's beliefs but also does not shrink from describing the extremes that result. To avoid care by the satanic forces of modern medicine and hospitals, third degree burns, bone breakage and traumatic brain injuries are treated with homemade remedies and energy channeling. All the kids work with incredibly dangerous, often improvised equipment in the family metal scrapyard. For example, a set of 3 ton shears instantly tears a gash in the author's brother's arm, and she actually refuses her father's direct order to man the huge scissors after his injury. The narrative brims with hideous accidents, partially due to the rigors of hands-on work,and partially attributable to the extreme version of self-reliance and make-do decreed by the father. Two dreadful car crashes resulting from stubborn insistence on driving all night seriously injure her mother and other family members. A scrapyard accident burns the flesh off her father's body, but mom just picks dead skin off with tweezers and applies miracle salve. It is astonishing that family members survive the maiming, burning and blunt force injuries. Naturally, the family believes that the healing is a sign of God's approval of their avoidance of modern medicine.
The other narrative thread is that of a family power struggle so extreme that the children are often forced to chose between total obedience to often crazy mandates and total exile from the family which is the only human community they have been allowed to know. An older brother Shaun violently abuses her, and it turns out has done the same to her older sister. However, as she approaches maturity, leavened with knowledge of the outside world, her story of abuse is discredited and the violence of the obviously mentally ill brother is excused and shielded. She learns how difficult it is to fight back against family abuse. "People who love you have power over you."
Westover struggles mightily with the demonization of her urges to get an education and understand more of the world outside the narrow precepts of the family ideology. Oddly when she gets to Brigham Young University, she discovers that the largely Mormon student body dresses in a way her family viewed as very immodest, and engages in all kinds of practices that would have enraged her father, from drinking Coke to reading works by "Satanic" authors.
How did this plucky gal extricate herself from this powerful, insular world view and not only go to college but win fantastic scholarships and degrees from the best universities? Extraordinary grit underpins the chapters of her life, even as she wavers in seeking family approval while pursuing her own education. Defying her family she studies any books she can grab at the town's library and practices algebra and trig until she can solve equations and pass the ACT college admission test-- all with no teachers and no previous education other than Bible study.
The description of the depredations of father and brother are suffused with toxic masculinity under the guise of religion, yet actually so intertwined with mental illness and traumatic brain injuries, it's hard to apportion fault. The memoir is of course also a bildungsroman, and Westover gradually realizes that ignorance of the world is preventing her from knowing herself. She is already in her 20s when an NYU professor tells her "find out what you are capable of, then decide who you are." To an outsider, a city-living secular humanist, these people are so off the charts fanatic, it's hard to accept that this is actually a mindset that is fairly common in certain areas of the US. While it features its own version of nutty and dangerous convictions, one also sees the impact of the fact-free Fox news, evangelical playbook of suspicion, authoritarian rule and weirdness.
