On the anniversary of his beloved wife's death, Dr. Michael Everett receives a letter Hannah had written him. In it she reminds him of her love and makes one final request. An impossible request. I want you to marry again. She tells him he shouldn't spend the years he has left grieving her. And to that end she's chosen three women she asks him to consider. During the months that follow, he spends time with Winter, Leanne, and Macy, learning more about each of them and about himself. Learning what Hannah already knew. He's a man who needs the completeness only love can offer. And Hannah's list leads him to the woman who can help him find it.
