The bestselling author of The Devil Wears Prada and When Life Gives You Lululemons is back with a delicious novel about a trio of best friends in Manhattan who agree to change their lives in the most personal and dramatic way possible—and to do it 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...and they’re not quite sure they like what they see.

When they are each alone on Valentine’s Day, the trio makes a pact. Within one year, each woman will change the thing that most challenges her. For Emmy, 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 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 and unforgettable characters. Let the games begin!
