A Lost Lady by
Willa Cather

Portrait of a frontier woman who reflects the conventions of her age even as she defies them. 

To the people of Sweet Water, a fading railroad town on the Western plains, Mrs. Forrester is the resident aristocrat, at once gracious and comfortably remote. To her aging husband she is a treasure whose value increases as his powers fail. To Niel Herbert, who falls in love with her as a boy and becomes her confidant as a man, Mrs. Forrester is by turns steadfast and faithless, dazzling and pathetic: a woman whose charm is intertwined with a terrifying vulnerability.
