Just Another Night — Elisa Adams

A one-night stand with an anonymous stranger is Erica's temporary escape from her mundane life. In the morning, she's perfectly content to pretend the whole thing never happened. But Erica should have known that nothing in her life is that easy. Soon enough she will come face-to-face with the masculine, virile man she hadn't ever planned to see again -- only to find out that his name is Nick Wilson...

And that he's her new boss.
