I think I have a better understanding of what she wrote as I read the prologue and first chapter of her book last night (available online).
The author claims that she was raised by her grandparents because her father was mentally incompetent and her mother walked out. She claims that her mother walked out because of the condescension and rigidness of her father’s Satmar family. She (the author) seems to not fit in, not to her family, nor to her community. She grew up feeling very little love, and she paints the Satmar community as people that like to “improve” others by meanly chastising them. The person who really ran her family was her aunt, who she really paints as self-righteous, controlling, and mean spirited.
Her story shows a lot of dysfunction in her family. It seems that the only person that showed her any love was her Bubby. She says that Bubby was OK with her reading secular books, but her Zaidy would have been really upset.
She has an independent, free-spirited personality (according to the psych eval she was forced to take) and that facilitated a rejection of a rule based lifestyle.
