Jack Prescott waited twelve years for his wife, Caroline. And then, the moment he found her again, he almost lost her.

The son of a violent drunk, Jack grew up on the streets, and he understands better than anyone how cruel and dark the world can be. As a martial artist and former Army Ranger, though, he knows how to take care of himself and those he loves. Only one thing can bring him to his knees—the thought of someone harming Caroline.

So he made it his mission to teach her self-defense...but not all of their time on the workout mat is work.

When a violent monster of a man breaks into Caroline's bookstore on Christmas Eve, Jack races to her side, all the while hoping his lessons have sunk in, because without her, life isn't worth living.
