For teenagers Sam Turner, Suzie Epstein, and Bella Spade, life in a New York suburb is a jumble of friendships and young crushes, complicated but retaining some innocence. This insulated world collapses in the aftermath of family break ups and the path to becoming grown-ups is suddenly more complex. Over the next decade, Suzie and Bella barrel through college and into relationships. Sam drifts about switching jobs, and they all reshape their ties to aging parents. Despite stumbles and losses, each finds a way to adulthood, sometimes aided and sometimes held back by their childhood bonds.
