Marquis de Sade 
Justine 

Justine, aged twelve sets off to make her way in France. The book follows her until age 26, in her quest for virtue. She is presented with sexual lessons, hidden under a virtuous mask. The unfortunate situations include: the time when she seeks refuge and confession in a monastery, but is forced to become a sex-slave to the monks, who subject her to countless orgies, rapes, and similar rigours.
