The bestselling author of Devil Wears Prada and Everyone Worth Knowing returns with the story of three best friends who vow to change their entire lives…and change them fast.

Emmy is newly single, and not by choice.

Leigh, a young star in the publishing business, is within striking distance of landing her dream job as senior editor and marrying her dream guy.

Adriana is the drop-dead gorgeous daughter of a famous supermodel.

Three very differing girls have been best friends for a decade in the greatest city on earth. As they near thirty, they’re looking toward their future…but despite all they’ve earned-first-class travel, career promotions, invites to all the right parties and luxuries small and large – they’re not quite sure they like what they see…

One Saturday night at the Waverly Inn, the girls make a pact: within a single year, each will drastically change her life. Their friendship is forever, but everything else is on the table. Three best friends. Two resolutions. One year to pull it off.

Let the games begin.
