The Californians, her first novel in set the post-Spanish era. Critics received this much more positively than Patience, and a review in The Spectator (October 1, 1898) said it "was by far more convincing and attractive in delineating California manners and morals.... The novel fairly establishes her claim to be considered as one of the most vivid and entertaining interpreters of the complex characters of emancipated American womanhood." The November 8 Bookman said it was her "most ambitious work," which has "a feeling of surety that only the consciousness of knowing one's ground can convey." She traveled to Rouen and wrote American Wives and English Husbands (1898), set in contemporary time. In this novel, she contrasts English and American men, American and English civilizations, and comments on the relationships between men and women.

The series includes The Splendid, Idle Forties (1902); The Conqueror (1902), which is a fictionalized biography of Alexander Hamilton; and her sensational, semi-autobiographical novel Black Oxen (1923), about an aging woman who miraculously becomes young again after glandular therapy.
