Identical twins Isabella and Hà were born in Vietnam and raised on opposite sides of the world. Hà was taken in by their biological aunt, and grew up in a rural village. Loan spent time in an orphanage before a wealthy, white American family adopted her and renamed her Isabella. But when Isabella’s adoptive mother learned of Hà back in Vietnam, all of their lives changed forever. Award-winning journalist Erika Hayasaki spent years and hundreds of hours interviewing each of the birth and adoptive family members and tells the girls’ incredible story from their perspectives, challenging conceptions about adoption and what it means to give a child a good life. Hayasaki contextualizes the sisters’ experiences with the fascinating and often sinister history of twin studies, the nature versus nurture debate, and intercountry and transracial adoption, as well as the latest scholarship and conversation surrounding adoption today, especially among adoptees.
