Twin sisters Hana and Kei grow up in a secluded Hawaiian town during the 1950s and 1960s, sharing an intense bond under the care of their loving yet unstable mother. Living without a father and within a mixed-race community, they experience a life of dreamlike isolation until their world is irrevocably altered by a harrowing betrayal. Years after being torn apart, Kei reappears on Hana's doorstep in Manhattan with a life-changing secret. 'Shadow Child' weaves together their narratives across the gritty streets of New York and the vibrant yet perilous landscapes of Hawaii. Set during the tumultuous period of World War II and its aftermath, including the Japanese internment camps and the bombing of Hiroshima, the novel explores themes of identity, family, and redemption. It's a tale of volcanoes, tsunamis, abandonment, and war, providing vivid context to the deeply personal stories of motherhood, sisterhood, and the hope for second chances.
