Shannon O'Connell is sixty-five but looks twenty years younger, though her life feels anything but vibrant. Her partner of thirty years left her with the cliché, "I love you, but I'm not in love with you," choosing a mutual friend instead. Her mother is disappearing into the depths of dementia, and now, the death of her best friend, Linda, from metastatic breast cancer has left her reeling. Shannon is broken, struggling through a dark night of the soul where every aspect of her life seems to be ending.

Yet, in this place of loss, an unexpected beginning takes shape. The "Tribe," Linda's lifelong group of friends, gathers at Shannon's family beachside resort to celebrate her memory. Though the reunion brings some solace, it's the presence of Elizabeth Matthews, an old flame, that stirs something long dormant within Shannon.

Elizabeth is as stunning and captivating as Shannon remembers, reigniting feelings Shannon thought had faded with time. But as they reconnect, both women must confront emotional roadblocks-old wounds, fears, and the protective walls they've built after years of disappointment.

Shannon is left wondering: can they navigate the scars of their pasts and find love again? In the midst of loss and heartbreak, is it possible that this Third Act of life could be her most fulfilling yet?

As she embarks on this unexpected journey, Shannon begins to hope that falling in love once more might just be the fresh start she never saw coming.
