One night a foreign business analyst in Tokyo sits down in his spacious high rise apartment and begins typing something. The words pour out and exhaust him. He soon realizes that the words appearing on his laptop are memories of his first days in Nagasaki four years ago. Nagasaki was a place full of spirits, a garrulous Welsh roommate, and a lingering mystery.Somehow he must finish the story of four years ago--a story that involves a young Japanese girl, the ghost of a dead Japanese writer, and a mysterious island. He must solve this mystery while maneuvering the hazards of middle management, a cruel Japanese samurai, and his own knowledge that if he doesn't solve this mystery soon his heart will transform into a ball of steel, crushing his soul forever. Though he wants to give up his writing, though he wants to let the past rest, within his compulsive writing lies the key to his salvation.
