I have been an old fan of Lauren Weisberger and have read all her books.
My favorite is Chasing Harry Winston and second favorite is Everyone Worth Knowing. She gained fame with Devil Wears Prada.
All her books fit into chic lit genre.
Her books provide an overview of aspirational lifestyle with fashionable clothes, parties and food.
The books show lovely female bonding and cover the journey of women aspiring to have a great career and amazing relationships.
Reading these books generally feels like eating frothy ice creams. The books also emphasize and sort of promote women to be more of their natural selves and help them be less fashion conscious and still feel comfortable.
