nThea Erickson, a renowned surgeon, is filled with both joy and grief as her family gathers at their home on a summer night in 1995. Her elder daughter Phoebe is getting married, but even the happiness of the day feels bittersweet, as Thea grapples with a terminal cancer diagnosis. She worries she won't be around to support her younger daughter Astra, who's still in college, but even Thea cannot foresee what is to come--a terrible accident the night of the wedding that changes Astra's life forever.n nIn a last-ditch effort to protect her family, Thea arranges a secret meeting with an old family friend and extracts a promise that will reverberate long after she's gone.n nYears after her mother's death, Astra has moved forward with a career and relationship, but she still struggles with her grief.

When a man reaches out to her and Phoebe, offering a window into their mother's past, Astra must make a choice, and her decision forces her to face what it means to love someone after they're gone, who we decide to forgive, and how families reckon with the past.n
