My Wish is You by Barbara Gee

What are you supposed to do when you meet a man you can’t help but fall in love with, and then he walks out of your life and disappears?
That’s what Janna Keller would like to know. She fell hard for Beckett Foster, FBI agent and top volunteer at the non-profit where she works. Smart, gorgeous, and passionate about helping victims of human trafficking–the man drew her from the beginning. But then his job took him away. A dangerous job. And Janna has no idea if he’s dead or alive.
Beck is alive all right, and Janna is never far from his thoughts. He’d hated walking away from her, but it had been for the best. It had even crossed his mind that maybe the timing of this assignment was God’s way of protecting her from a man burdened with a messed up past and a job that made a long term relationship impossible. A woman like Janna could do so much better.
Janna doesn’t agree. When Beck comes back into her life after an endless year of waiting and promptly renews his efforts to push her away, she doesn’t go far. And as Beck slowly comes to terms with lingering issues of hurt and guilt from years ago, a way to make it work with Janna opens up. He dares to hope, and then another test comes their way. A girl who was taken against her will and put on the streets needs help, fast, and her best chance is Beck.
He has to go. One last job. What he doesn’t know is that this one will threaten to take Janna from him, just when he’s finally allowed himself to dream of a life that includes her.
If they can survive this “one last job,” they can survive anything. With God’s mercy and guidance, that’s exactly what they’ll do.
