Everyone Worth Knowing (English, Paperback, Lauren Weisberger)

What happens when a girl on the fringe enters the realm of New York’s chic, party-hopping elite?
Soon after Bette Robinson quits her horrendous Manhattan banking job like the impulsive girl she’s never been, the novelty of walking her four-pound dog around the unglamorous Murray Hill neighborhood wears as thin as the “What are you going to do with your life?” phone calls from her parents. Then Bette meets Kelly, head of Manhattan’s hottest PR firm, and suddenly she has a brand-new job where the primary requirement is to see and be seen inside the VIP rooms of the city’s most exclusive nightclubs. But when Bette begins appearing in a vicious new gossip column, she realizes that the line between her personal life and her professional life is…invisible.
