Problem: In a word, Lacking. Her style of writing left me unable to appreciate the underlying story which, as a result, I found rather vacuous and inauthentic. So much so that I felt compelled to come write a review of this book so others might avoid making the same mistake I did. No offence Patricia.
Solution: Negative
