I have a copy of her book but haven't read it. However I have read the amazon reviews, hah.
The reviews indicate that it's about her views on her identity. Critics say that the book is self-indulgent and narcissistic.
But I can kind of understand how someone who is extremely good looking and makes millions with very little work can have a 'warped' mindset vs. ordinary people who have to work the fields...
Basically, she's someone who was groomed to use her beauty to maximum leverage (like her beautiful mother) for wealth and status. The book is a personal accounting of the consequence of her choosing this path and her deep, existential dissatisfaction with her life. She has the money, could date really wealthy men for years, lives in the city, but feels empty/like an elite prostitute.
