Now in paperback—from the bestselling author of The Devil Wears Prada and Everyone Worth Knowing—a "glitzy Manhattan romp" (People) about a trio of best friends who vow to dramatically change their entire lives within one calendar year.

Meet Emmy, Leigh, and Adriana. Best friends since college, each has seen her share of career foils and romantic foibles over the past decade. Now, as they approach thirty, they’re looking toward their future...but despite all the success and luxuries they’ve attained—they’re not quite sure they like what they see.

When they are each alone for one reason or another on Valentine’s Day, the trio makes a pact. Within one year, each woman will change the thing that most challenges her. For Emmy, whose boyfriend of five years just left her for a personal trainer, it will be to find romance—or a fling—in every foreign country she visits. For Leigh, a book editor with a dream boyfriend and dream apartment, no change seems necessary—until she starts to notice a brilliant and brooding man named Jesse. And for commitment-phobic, drop-dead-gorgeous Adriana, her goal is to have an engagement ring and a house in Scarsdale. Each woman starts the first day of the year with the best of intentions—which is exactly why the pact goes immediately, and exceptionally, awry.

Filled with delicious insider details, Chasing Harry Winston whisks readers into the heart of an elite world, where friendships will be tested to the point of breaking, and showcases Weisberger’s best storytelling efforts to date.
