Nuisance by Jennifer Griffith

She dreamed about kissing a stranger. Then he showed up in her courtroom—trying to take her job.

Camilla Sweeten, county prosecutor, has a big problem. Well, several, but the weirdest one is that her dreams are coming true. Literally. Not her life dreams, but those weird dreams that occur just before she wakes. And it’s unsettling, because some of them involve making out with a stranger in a room full of floating law books.
While she should have her eyes riveted on the promotion to chief deputy county attorney, which she’s worked for so long, she can’t seem to take her eyes off the gorgeous, newly hired competition for the job.

But he’s such an attractive nuisance.
