In memories that rise like wisps of ghosts, LuLing Young searches for the name of her mother, the daughter of the Famous Bonesetter from the Mouth of the Mountain. Trying to hold on to the evaporating past, she begins to write all that she can remember of her life as a girl in China. Meanwhile, her daughter Ruth, a ghostwriter for authors of self-help books, is losing the ability to speak up for herself in front of the man she lives with and his two teenage daughters. None of her professional sound bites and pat homilies works for her personal life; she knows only how to translate what others want to say. Ruth starts suspecting that something is terribly wrong with her mother. As a child, Ruth had been constantly subjected to her mother's disturbing notions about curses and ghosts, and to her repeated threats to kill herself, and was even forced by her mother to try to communicate with ghosts. But now LuLing seems less argumentative, even happy, far from her usual disagreeable and dissatisfied self. While tending to her ailing mother, Ruth discovers the pages LuLing wrote in Chinese, the story of her tumultuous and star-crossed life, and is transported to a backwoods village known as Immortal Heart. There she learns of secrets passed along by a mute nursemaid, Precious Auntie; of a cave where dragon bones are mined, some of which may prove to be the teeth of Peking Man; of the crumbling ravine known as the End of the World, where Precious Auntie's scattered bones lie, and of the curse that LuLing believes she released through betrayal.
