I think expecting a book written by a person specifically about themselves and analysing their own experiences to be anything other than in-depth talking about themselves is a bit misguided. And sounds like SH needed to write it with regards to the traumatic experience mentioned.
The review is good; I can't imagine a book about not doing something is going to be very interesting to me but the questions it asks/could have asked are worth asking.
I follow SH on SM and she used to be quite funny but obviously promoting the book it's all been a lot of 'I'm fat' and 'I'm not having sex' and I know there is far more to Sophie than that. But I guess sex sells even if you're not having it.
"Since she is a sex positive person, albeit sexlessly sex-positive, there’s no room in Hagen’s philosophy to ask whether part of the problem is the commodification of intimacy." This would have been interesting!
