Don't Tempt Me (Pearl Island Trilogy #3)
Julie Ortolon

As the owner of the Pirate's Pleasure, Jackie Taylor is far more interested in running her cruise ship along the Texas coast than in chasing tales of lost booty, and even less interested in tangling with a man who collects female admirers just by walking down the street. On top of that, helping the St. Claires could dredge up secrets she'd like to remain buried.
Enticed by Jackie's resistance, Adrian soon has something more than treasure hunts and casual flirtation in mind...and he's not a man who takes no for an answer. But will they each have the courage to risk their hearts for the greatest treasure of all--falling in love?
