In "Cinderella & Company," Pulitzer Prize-winning journalist Manuela Hoelterhoff takes us on a two-year trip on the circuit with Cecilia Bartoli, the young mezzo-soprano who has captured an adoring public around the world. Here too are tantalizing glimpses of divinities large and small: Kathleen Battle's famously chilly limousine ride; Placido Domingo flying through three time zones to step into the boots of an ailing Otello; Luciano Pavarotti aiming for high C in his twilight years. And we meet the present players in Bartoli's world: Roberto Alagna and Angela Gheorghiu, a.k.a. the Love Couple; Jane Eaglen, the Wagnerian web potato monitoring her cyberspace fan mail; the appealing soprano Renee Fleming, finally on the brink of stardom.
