Bette finds herself working for Kelly & Co., where she is tasked with planning parties, eating and drinking at the city's most fashionable night spots, and becomes a regular subject of a popular online gossip column, whose anonymous author seems determined to link her romantically to wealthy playboy Philip Weston.

While she finds Philip somewhat attractive and the association becomes of great benefit to her in her new job, she is later drawn to Sammy, a bouncer at Bungalow 8, a New York City nightclub, who is from her hometown of Poughkeepsie and harbors ambitions of being a chef.

[2] Like The Devil Wears Prada, Everyone Worth Knowing is essentially a morality play in which an unglamorous young single woman is suddenly thrust into a glamorous New York City industry and slowly becomes comfortable in it, despite keeping herself at a distance.

Unlike the novel's predecessor, however, it depicts far more decadent behavior from its wealthy elite, including casual sex, frequent illegal drug use, and women starving themselves to the point of passing out from sheer hunger.

Although in most countries the book has the same title, or a direct translation, the title in some European countries is Gossip and Gucci, but in Spain the book is called How to be the coolest in New York, in Finland VIP-ihmisiä (VIP-people), in Sweden Alla var där (Everyone was there), in Greece Η βασίλισσα των party (The queen of parties)[3] and in Italy is Al diavolo piace Dolce (The devil likes Dolce "& Gabbana").

Bette's guilty pleasure leads to many romance novel titles, possibly fictional, being mentioned, such as The Very Bad Boy and Her Royal Bodyguard.
