Delia Vittoria's mother has lost her voice at last. After five years of being her diva mother's understudy, it is time for Delia to assume her place as the lead soprano on stage behind the Academy of Music's faded velvet curtain. And she is all that stands between the Academy and its greatest threat—the nouveaux riche's lavish new Metropolitan Opera House. Kit Quincy never misses opening night, but when his sister begs him to help get her husband out of an Italian opera star's arms, Kit confronts the wrong Lady Vittoria. When he happens upon the stunning young diva again at Mrs. Astor's dinner the following night, he attempts to make amends and is instead pulled into a plot to win the great opera war. To draw attention to Delia Vittoria as the new soprano star, Kit is convinced to act as both Delia's patron and the enigmatic phantom who once haunted the Academy years ago. But when a second phantom appears, more than Delia's rising career is threatened.
