manga

Victoria was handpicked to be an assistant by the crown prince of the desert kingdom of El Deharia. So then why would the Imperial Guard suddenly break into her room and drag her away wearing nothing but a negligee? Her good-for-nothing father has been in trouble for gambling before, but to think he would have tried to cheat at cards against Prince Kateb... The prince's personality is as fierce as his scarred face. He earned the scars amid a failed kidnapping, during which they say he killed a man. Rejecting palace life, he has been known to disappear to a desert village for months at a time. Victoria despises her father, but can't abandon the promise she made to her dying mother. She pleads with the prince to set him free, and the prince agreed...on one condition. She would become his lover, and join his desert harem! (Source: Harlequin)
