Alexandre Dumas 
Camille [EPUB ebook] 

Armand falls in love with Marguerite and ultimately becomes her lover, convincing her to turn her back on her life as a 'courtisane’ and live with him in the countryside.
This idyllic existence is broken by Armand’s father, who, concerned by the scandal created by the illicit relationship and fearful that it will destroy his daughter’s (Armand’s sister’s) chances of marriage, convinces Marguerite to leave Armand, who believes, up until Marguerite’s death, that she has left him for another man.
