Meanwhile, Vietnamese American Vivi Huynh, has never been to Việt Nam. Her parents rarely even talk about the homeland that clearly haunts them. So Vivi secretly goes to Vietnam for a study abroad program her freshman year of college. She’s determined to figure out why her parents left, and to try everything she’s seen on her favorite food blog, A Bánh Mì for Two.
When Vivi and Lan meet in Sài Gòn, they strike a deal. Lan will show Vivi around the city, helping her piece together her mother’s story through crumbling photographs and old memories. Vivi will help Lan start writing again so she can enter a food blogging contest. And slowly, as they explore the city and their pasts, Vivi and Lan fall in love.
