Kezia Cooper Hobson, recently widowed, arrives in New York from San Francisco. Determined to make a fresh start, she has just completed the sale of her Pacific Heights home, not to mention her husband's venture capital firm, and in doing so, is also freed from her responsibility as a board member of the company. Bringing with her only a few personal treasures, she is excited to move into the blank slate of a beautiful midtown penthouse, in the city that she has always loved. It is also where her two adult daughters now live.

As Kezia settles into her new apartment, she meets her movie-star next-door neighbor, Sam Stewart, whose terrace borders hers. Just a couple of weeks after she arrives, however, a devastating crisis strikes New York City. Kezia and Sam find themselves connecting over their strong impulse to help those in need. As they share a life-changing experience of volunteering, a bond is sparked and a friendship is formed.

Kezia's daughters, Kate and Felicity, are taken aback by their mother's new friendship, both more focused on their own love lives than hers. But Kezia is learning that the changes she's making are just what she needs to open new horizons.
