When three-year-old Benji is plucked from the security of his home in Nagasaki to live with his American father, Lt. Benjamin Franklin Pinkerton, and stepmother, Kate, on their farm in Illinois, the family conceals Benji’s true identity as a child born from a liaison between an officer and a geisha-and instead tells everyone that he is an orphan. When the truth surfaces, it will splinter this family’s fragile dynamic and send Benji on the journey of a lifetime from Illinois to the Japanese settlements in Denver and San Francisco, then across the ocean to Nagasaki, where he will uncover the truth about his mother’s tragic death.
