When she marries the Crown Prince of Japan in 1959, Haruko is met with cruelty and suspicion by the Empress, and controlled at every turn as she tries to navigate this mysterious, hermetic world, suffering a nervous breakdown after finally giving birth to a son. Thirty years later, now Empress herself, she plays a crucial role in persuading another young woman to accept the marriage proposal of her son, with tragic consequences. Based on extensive research, The Commoner is a stunning novel about a brutally rarified and controlled existence, and the complex relationship between two isolated women who are truly understood only by each other.
