At the centre of this epic tale are enigmatic Sparrow, a genius composer who wishes desperately to create music yet can find truth only in silence; his mother and aunt, Big Mother Knife and Swirl, survivors with captivating singing voices and an unbreakable bond; Sparrow's ethereal cousin Zhuli, daughter of Swirl and storyteller Wen the Dreamer, who as a child witnesses the denunciation of her parents and as a young woman becomes the target of denunciations herself; and headstrong, talented Kai, best friend of Sparrow and Zhuli, and a determinedly successful musician who is a virtuoso at masking his true self until the day he can hide no longer. Here, too, is Kai's daughter, the ever-questioning mathematician Marie, who pieces together the tale of her fractured family in present-day Vancouver, seeking a fragile meaning in the layers of their collective story.
