Heiress Evangeline "Lindy" Lindenmayer has been groomed since childhood to marry into the British aristocracy as her mother's ultimate ambition is a royal title for the family name. But literature fascinates Lindy far more than ballgowns, and she spends all her free time in the library, the only room in the Fifth Avenue mansion where she can safely indulge her passion for reading and find refuge from the prying eyes of her mother.

Jack Winthrop is studying for the ministry at Union Theological Seminary and has been invited to use the Lindemayer's library for his studies. His sole experience of upper-class young women has occurred at his uncle's church, where he has found these young debutantes universally featherbrained. When he meets Lindy, he is pleasantly surprised to discover she has wide-ranging interests and is highly intelligent. Although cautioned by his uncle to stay away from her, he finds Lindy a kindred spirit and over animated discussions of books and life, they fall in love.

But to reach happily ever after, Lindy will need to challenge her mother's long-laid plans, and weathering the approaching storm will take more backbone than she even knew she had.
