When twin girls are adopted out, one remaining in Vietnam and one moving to America, notions of family are challenged. Erika Hayasaki is a professor in the Literary Journalism Department at the University of California, Irvine, and she joins host Krys Boyd to discuss two sisters raised worlds apart and the questions that arise about transnational adoption. Her book is “Somewhere Sisters: A Story of Adoption, Identity, and the Meaning of Family.”
