Renowned petroleum geologist Bree Hart's blood, sweat, and tears have put her sexist father Duke Hart's Dallas firm, Hart Enterprises, on the international map. So when he brazenly appoints her cousin Caleb Hart, a former bull rider with little relevant work experience, to lead HE, Bree walks. She takes a job with real leadership responsibility at Wells Oil, one of Hart Enterprises's competitors . . . and the real drama begins. Bree thinks she's landed the position because of her top-notch skills, but billionaire oil tycoon Grayson Wells's motives are not noble. Grayson believes Duke Hart swindled his father out of his oil field and fortune, leaving him, his dying mother, and autistic brother mired in poverty for decades. Now, years after winning a lucrative oil field in a high-stakes poker game in Dubai, the dashing con artist Grayson is back in Dallas to steal Duke's kingdom and get his family justice-and he plans to use Bree to achieve his ends. But Grayson hasn't counted on Bree's beauty, boldness, caring nature, and intellectual fire to stoke a flaming sexual desire in him that he can't quell. Problem is, Bree's battling her own wild attraction to her impeccably groomed, brawny stud of a boss. For Grayson, the stakes are high: In bringing Duke Hart down, he'll hurt Bree. His heart wants him to be with her, but his brain knows better. Will Grayson stay focused on destroying Duke? Will Bree get steamy thoughts of Grayson off her mind and stay focused on the high-responsibility job she was born to do? Or will the lure of amazing sex-and possibly real love-derail their plans? Will these two stop Chasing Hearts?
