In the realm of performing classical musicians, the stakes are high, the champagne is good, and the competitors can be ruthless. Merrill Lyman has a life most people envy. As an internationally famous flutist, she gets plenty of money and adoration. But she's had her share of problems too: a media frenzy around the break up of her first marriage to a philanderer, a dependent young lover, and now she is afraid for her sanity. Phantom notes echoing her own are plaguing her. When she discovers the secret behind the ghostly tones, her problem becomes how to stay alive when a jealous rival wants her dead.
