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.
