The Devil Wears Blue Jeans by Mary J. Williams

Dark and irresistible, they call him the Devil for a reason.

The moment he touched her, held her, kissed her, she knew the dangers. She should have said no.
But unlike him, she was only human.
When Joshua McClain is hired as the Seattle Knights new head coach—a move that raises more than a few eyebrows—he’s determined to prove he’s not the same hot-headed troublemaker he was in his playing days. However, when he meets beautiful, exasperating, irresistible Darcy Wells, his good intentions are put to the test.
As the first woman general manager of an NFL team, Darcy knows she has a lot to prove and everything to lose. She can’t afford to let herself be distracted by any man, let alone the impossibly arrogant Joshua McClain.
Joshua and Darcy have two goals. First? Return the Knights to their Super Bowl-winning glory days. Second? Do everything in their power to keep their hands off each other.
What happens when an almost reformed bad boy and a good woman with an unexpected wild side clash? Turns out there might be just enough devil in him and her to satisfy them both.
