Her Gentle Giant by Carolyn Faulkner

Arianne Messier managed to get away from her abusive husband, settling with her young daughter in a small town in Tennessee at the base of the Smoky Mountains.
There, she meets a man who is even bigger than her husband was, and she keeps ending up having to deal with him when she’d really rather not.
Hoyt Chandler is a war hero who bears the scars, literally, to prove it. He’s a bit crotchety at first and doesn’t think he’ll ever find a woman who will be able to look past how ruined he is.
But could Arianne be that woman? Could it be that they were meant to heal each other? Publisher’s Note: This contemporary romance contains a theme of power exchange.
