I agree with others who wrote that she comes across as genuine. It sounds like she had a particularly difficult upbringing and her situation seems to be different than most. I am not Chassidish but she does seem to be attacking the general Chassidic group and not focusing on her particular Chassidis and more importantly her family and the people arround her who certainly failed her. She does appear genuine but dont take that to mean that her intentions are pure. The purpose of this book is vindictive and agenda driven, it wouldnt get published otherwise. It is interesting to see this interview right after watching the Oprah show and see the stark contrast in how the two report the same obligations (namely Mikvah). She also describes the education of the women as sorely lacking (graduating HS with a 4th grade reading level) while the women on Oprah seemed just as educated as she is if not more, getting Masters degrees and having legitimate professional occupations.
Its all about perspective and if you have a strong agenda then your perspective is very skewed and unreliable.
