England between the wars was a paradise of calm and leisure for the very, very rich. Into this enclave is born Mrs. Emmeline Lucas–La Lucia, as she is known–a woman determined to lead a life quite different from the subdued formality of her class.

With her cohort, Georgie Pillson, and her husband, Peppino, Lucia upends the greats of high society: the imperious Lady Ambermere and her equally imperious dog, Pug; the odious Piggy and Goosie Antrobus; the Christian Scientist Daisy Quantrock, with her penchant for the foreign; and all the rest of the small English town that the British rich call their country home. Beset on all sides by pretenders to her social throne, Lucia brings culture, fine arts, excitement, and intrigue into this cloistered realm.
