Flashlight begins with the disappearance of Serk, a Korean émigré and academic, during a walk on along the coast in a small Japanese town with his young daughter, Louisa. While Serk is presumed drowned, Louisa washes ashore hours later, traumatized and unable to recall what has happened. The books subsequently spans decades and continents, as Louisa and her American mother, Anne, struggle to cope with their grief and the mystery of his vanishing. This sits against the complex geopolitical backdrop of the late 20th century, particularly focusing on the lives of Korean immigrants in Japan and the unsettling history of North Korea.

Pearl tells the story of Marianne, a young mother who is reflecting on the loss of her own mother, who disappeared (presumed dead) when she was eight years old. Left with her father Edward and baby brother Joe, she has spent her life struggling to understand her mother’s motives, grieving both for her mother and for the family home which they had to abandon in the wake of her loss.
