Korean adoptee and Canadian Jenny Heijun Wills, 39, talks about her 2019 acclaimed memoir, Older Sister. Not Necessarily Related. It's about her relationships with her first family after being reunited in a form of a letter to an older biological half-sister, separated by time, language, boundaries, child removal and international closed adoption. and parental failings. The book also bravely addresses inter-adoptee harm, ways marginalized communities protect and hide sexual assault amongst their own kin, and the fears that come with breaking that code.
