Fiction. Asian American Studies. In sunny California, the Vietnam War may have just ended, but nine-year-old Helen Johnson's world is beginning to crumble. Her father, a former POW and Vietnam veteran, has become increasingly distant; her mother, a Japanese adoptee, is struggling with mental illness; and her six-year-old brother is too young to understand what's happening. Determined to find out more about her mother's past and with a boldness that belies her timid self-image, Helen writes to her great-uncle Hideo in Japan, beginning a journey that will take her across the ocean and through the imperial legacies of both countries.
