Courtney, Norah, and Raine Cassel are as different as three sisters can be. Norah, the oldest, is a type A obsessive who hasn't forgiven Raine, the middle sister, for ruining her wedding day six years ago. Raine is Norah's opposite, a wild child/performance artist/follow-your-bliss hippie chick who ran off to California . The only thing the two have in common is their ability to drive Courtney, their youngest sister, crazy.

When her longtime boyfriend proposes, Courtney decides it's finally time to call a truce and bring the three sisters together. After all, they're grown-ups now, right? But it turns out that family ghosts aren't easily defeated--and neither are first loves. Soon Courtney finds herself reexamining every choice she has made in the past six years--including the man she's about to marry--and the value of reconnecting with the sisters she knows she needs, in spite of everything.
