The Royals of Cordova, Book One: The Crown Princess, by Kathleen Samuels

Gwen:  Dependable Crown Princess of Cordova, Gwen, is dreading the day she gives up her life for her country. With the day of coronation looming, Gwen decides to make a bucket list of crazy things she wants to do before the big day.  Taking her list, she travels to Las Vegas, a place where no one will question wild behavior and she can be just another normal person on vacation in sin city.  Enlisting the help of Alex, a notorious entitled playboy, she finds herself checking off more than just the items on the list.

Is she willing to risk it all and take a chance at falling in love?

Alex:  Fiercely independent Alex, the black sheep of his family, was raised in the hotel business.  Breaking out on his own, he built a successful Resort and Casino on the strip in Las Vegas. When Gwen asks for Alex’s help on completing her list of ‘bad girl’ activities he readily accepts.  Who else knows how to let loose but the Billionaire Playboy himself?

But as he starts helping her with the list, he begins to realize that this Princess might be worth trading in his bad boy image.
