The novel tells the story of Mrs. Maitland, a leathery old widow who owns and operates an iron mill. Her devotion to a Puritanical work ethic alienates her son Blair, who though he stands to inherit the business, is headstrong and in love with Elizabeth Ferguson, a match Mrs. Maitland disapproves of. It was first published in installments in Harper's Monthly from November 1910 through October 1911.
