From a USA Today–bestselling author, a wealthy tycoon learns he has a son and battles with the boy’s beautiful aunt for guardianship, only to fall for her. When Alejandro Santiago discovers he has a young son, his money and power mean he easily wins custody from the boy’s aunt, Brynne Sullivan. But he hasn’t counted on Brynne being so feisty, passionate—and beautiful. He agrees to her plea for a month’s visit. There’s just one problem for Brynne: the Mediterranean millionaire is not just arrogant—he’s also infuriatingly gorgeous! As Brynne reluctantly gives in to the desire simmering between them, she knows that to Alejandro, she’s only a conveniently short-lived affair . . . .
