The Rush by Piper Westbrook

She’s his enemy in the game.

Once he was football’s hottest quarterback. Now he’s Sin City’s disgraced prince. A suspected criminal. A pariah. A bona fide badass. The fall from grace should crush any man, but Simon Smith has a vendetta against Veronica Greer, the woman who fired him.
He can see through the good girl reputation that hides all her dirty. She holds his career in her hands, but she belongs to him. When she offers to repair his image to appeal to another team, he knows it’s an attempt to deny themselves the inevitable: danger, greed, and destruction.

Challenge accepted.
