From fictiondb: "Sleeping rough not your thing anymore, little rich girl?" Alessandro Vallini once made the mistake of proposing to spoiled princess Rachel McCulloch. Her rejection scored his soul. But now the tables have turned: bad-boy-made-good Alessandro now holds Rachel's future in the palm of his hand! He needs a temporary housekeeper, and she needs money -- it's a perfect opportunity to taunt her with what she turned down.... Riches-to-rags Rachel is very different from the glittering socialite Alessandro remembers. He's laid his trap -- with himself as bait! -- but who's catching whom in this web of desire?
