In Philadelphia, good girl Kate is dumped by her fiancé the day she learns she is pregnant with his child. In New York City, beautiful stay-at-home mom Vanessa finds herself obsessively searching the Internet for news of an old flame. And in San Francisco, Dani, an aspiring writer who can't seem to put down a book—or a cocktail—long enough to open her laptop, has just been fired . . . again.
In an effort to regroup, Kate, Vanessa, and Dani retreat to the New Jersey beach town where they once spent their summers. Emboldened by the seductive cadences of the shore, the women begin to realize just how much their lives, and friendships, have been shaped by the choices they made one fateful night on the beach eight years earlier—and the secrets that now threaten to surface.
