When the Past comes calling

Addison Montgomery has built a full, loving life in Los Angeles with her wife, Meredith Grey. Together, they work at Saint Ambrose Hospital-Meredith as a general surgeon, Addison as a renowned neonatal and fetal surgeon-while raising their four children. It's a life grounded in purpose, family, and the belief that some chapters are finally behind them.
Then the past calls.

A phone call from Addison's former mentor, Richard Webber, pulls her back into a crisis she can't ignore. Jo Wilson is facing a life-threatening medical emergency. Pregnant with twins and struggling with a severe heart condition, Jo's life-and her babies'-hang in a fragile balance. The case is complex, rare, and unforgiving, and Addison may be the only doctor capable of giving them a chance.

Before returning to the operating room, Addison travels to Seattle to be with her sister, Amelia Shepherd, who is mourning the loss of her late girlfriend, Monica. In the midst of grief, Amelia is reunited with Addison, Meredith, and their children-a reminder that love endures, even after devastating loss.
At its core, When the Past Comes Calling is a story about

answering difficult calls, carrying grief without letting it harden you, and fighting for life when the odds are stacked against you. As Addison steps back into a world that shaped her, she must confront the truth that some lives are worth risking everything for-and some calls can never go unanswered.
