The sound of the harpsichord penetrated the depths of my heart. Slowly, it filled that darkness where neither light nor language could reach. Fleeing from her unfaithful husband, the calligrapher Ruriko retreats to a country house in the mountains to work on a commission. Soon, she meets her neighbors: the pianist Nitta, who can no longer play in the presence of others and now builds harpsichords, and his assistant. Although Ruriko senses that invisible ties exist between Nitta and his assistant, she feels drawn to him, and a delicate love triangle unfolds. An extraordinary novel about the fleeting nature of happiness and the incomprehensible magic of music.
