Leonora [EPUB ebook] 

The plot of the novel centres on the newly married Leonora and her decision to bring back to England a woman who had been exiled to France. The woman, Olivia, is known as a "coquette, " and her controversial behaviour with regard to her marriage had driven her to France, where she cultivated an aristocratic, "French" sensibility that exists apart from conventional morality.
