Irish rose - Nora Roberts

Burke Logan was a gambler, and luck had made him owner of Three Aces, one of the finest stables in Maryland. He'd come to Ireland to buy horses, but one look at Erin McKinnon's fiery beauty told him that he'd be leaving with a whole lot more.
Erin McKinnon had dreams and ambitions--and no intention of living out her days in the small town of Skibbereen! She knew Burke held all the cards, but when he asked her to come with him to America, it was an offer she couldn't refuse. Burke Logan was a man to be reckoned with, and from the moment they met, Erin knew that even if she lost, she'd win.
