The Doctor's Nanny. Tennessee Tulanes

Showing up on her sister's doorstep several years after stealing her man might not be the smartest thing to do, but Megan Rose is out of choices. Sick, with $3 in her pocket and no gas in the tank, she's ready to eat as much crow necessary to get back on her feet and leave for good-hopefully having made amends. As much as his sister-in-law wants Megan gone, Ethan Tulane needs her to stay. She's the only one able to communicate with his newly-adopted, French-speaking son, who has a tendency to make a run for it at every opportunity like he's still trying to escape his war-torn country.
His son and Megan quickly form an unusual bond, and it isn't long before Ethan realizes they're both running scared and traumatized. He understands his son's behavior-but Megan's? His protective instincts screaming, Ethan is determined to uncover Megan's secret... *This book has a clean and wholesome version by Kay Lyons titled THE NANNY'S SECRET.
