There are multiple enigmas in this elegant, elegiac novel.  The unexpected arrival of boxes of mushrooms, the untold truths within a marriage, and a famous elderly pianist—all of these are among the mysteries this novel has to offer. It’s told from the point of view of Song Yan, a former concert pianist who gave up her career for marriage to her increasingly absent husband. To distract herself, she begins to visit Bai Yu, a legendary but aging pianist and plays for—and with—him. Meanwhile she discovers that her husband has been keeping secrets, and she gradually learns that Bai Yu himself is not all that he seems.  A book whose limpid, matter of fact prose dances beautifully on the edge of the real and the unreal, making you believe in both of them.
