Silent Night by Kathryn Kelly

Tabitha Black had found the perfect hiding place from her abusive soon to be ex-husband. He’d never find her in the small town of Estes Park, Colorado. She planned to keep her head down and her heart protected. She had to stay focused and survive six weeks to get through her divorce. But something about the boy next door had her attention and left her feeling safe. Protected.
Adam Patton had spent six years in the Air Force pararescue unit. He wanted nothing more than the quiet contentment of his small town shop. When the vulnerable Tabitha Black lands next door, he wants nothing more than to spend the holidays with her. But instead of celebrating the magic of Christmas, he must rescue her first.
As they settle into the magic of the Christmas season, Tabitha’s ex-husband not only finds her, but stalks her. As Adam fights to keep her safe, her stalker turns his attention on him. Can the two of them keep each other alive? Or will this Christmas turn tragic?
