One Wednesday afternoon in late September, Ann Veronica Stanley came down from London in a state of solemn excitement and quite resolved to have things out with her father that very evening. She had trembled on the verge of such a resolution before, but this time quite definitely she made it. A crisis had been reached, and she was almost glad it had been reached. She made up her mind in the train home that it should be a decisive crisis. It is for that reason that this novel begins with her there, and neither earlier nor later, for it is the history of this crisis and its consequences that this novel has to tell.
Ann Veronica describes the rebellion of Ann Veronica Stanley, "a young lady of nearly two-and-twenty", against her middle-class father's stern patriarchal rule. The novel dramatizes the contemporary problem of the New Woman. It is set in Victorian era London and environs, except for an Alpine excursion. Ann Veronica offers vignettes of the Women's suffrage movement in Great Britain and features a chapter inspired by the 1908 attempt of suffragettes to storm Parliament.
