Decades later, Coty struggles to repair the frayed bond between Jette, her often-absent, widowed daughter, and Evelyn, her only grandchild. Evelyn, at the behest of her grandmother, travels to Vietnam to locate a nun, Sister Lan, whom Coty has never met yet has been haunted by for many years. Evelyn persuades Sister Lan to return with her to San Francisco to meet Coty even as Coty invites Matheo Aubert, a visiting priest from Gabon, to move into her home as a guest during his reluctant sabbatical. The two foreigners are central, albeit unwitting, players in Coty's scheme to heal the rift in her family and her own wounds from the past. But if she is going to succeed in her quest, she must secure Jette's long-withheld permission to share a revelatory photograph--one that promises to change everything with Evelyn.
