Serena Graham is looking forward to the vacation of a lifetime-a week at Paradise Resort, a Caribbean hideaway where she'll be able to indulge her every sexual fantasy with complete abandon and total anonymity. For the next week, she's Sexy Siren Serena and she'll do whatever she wants-with whomever she wants.

Michael Donovan planned a week at Paradise Resort to research his next erotic crime novel, as well as indulge in some hot sex with his fashion model girlfriend. But when he finds his now ex-girlfriend has other plans, he's resigned to research without recreation. That is, until Serena shows up at his door claiming he's occupying her room.

After a little negotiating, Michael and Serena become roommates, and Serena boldly asks Michael to be her lover for the week. How can he pass up the opportunity to mix a little pleasure with business? But despite their vow to keep their relationship strictly physical, they find much more than passion in paradise.
