Synopsis:
Is a week of passion enough to warrant changing their lives forever?
Italian born Giselle Moore is reinventing herself for the second time in her short twenty-four years of life, trading in her bohemian artist’s life in Paris for the grit and glamour of New York City where the family she hasn’t seen in years awaits her. But before beginning her new life, she travels to Cabo San Lucas, Mexico searching for a week of relaxation and reprieve before barreling into her turbulent future.
She never expected to meet the handsome and enigmatic Frenchman Sinclair on the plane and she certainly never would have imagined herself accepting his proposal for a weeklong, no-strings-attached affair. Giselle has never experienced anything as heady as Sinclair’s controlled seduction and cool yet devastatingly erotic commands and she finds herself powerless to stop the ferocity of their passions, even when she discovers he has a partner back home. The last thing she needs in her life is another complication, yet as the week wears on, she finds it surprisingly easy to relinquish control to Sinclair, a man she knows nearly nothing about. And to her horror, the one thing she promised never to submit, her battered heart, is just as easily captured in the business mogul’s unyielding hands
