From the Back Cover:
A strange and forbidden passion..
 
Unhappy and restless after the breakup of a love affair, beautiful Laura Walker arrives in New Orleans. The glamorous city of cast-iron balconies and old-world charm seems the perfect place to start a fresh new life. 
 
But then she meets the Lecouveurs and is powerless to resist their mysterious attraction. Emory, patriarch of the city's most powerful dynasty is determined to control- and to ravish- everything he touches.
 
And Alain, Emory's fatally handsome nephew, is struggling against five centuries of unholy family tradition, even as he is pulled inexorably into their depths.
 
Alain is the destiny that beckons Laura, the destiny that demands she succumb to his raw embrace. For he is heir to an ecstasy the living can never know. He offers her a rapture beyond her dreams, fulfillment she never thought possible from a man...
