Falling for the New Guy (Harlequin Super Romance Series #1977)

She needs a distraction 

One of Bluff City's finest, Tess Camden always follows the rules. That means a romp with the strong and silent new guy on the force would be out of the question. Besides, no matter how deliciously sexy Marc Santino is, she's his boss. So she'll stick with her keeping-to-herself routine. 

Still, Marc has Tess aching to be all kinds of wrong. And all those reasons they have to stay away don't seem important…especially if their sexy arrangement remains their secret. Suddenly, their hot affair becomes more than just a distraction. Can they let it turn into something more?
