It seemed like a harmless holiday fling-until the guns came out. Deliver a gift. A seemingly simple mission until Mathias runs into some complications. Namely a clumsy lady with an obsession for sweaters. A woman who knows how to heat his blood without even trying. Snowmen aren't the only ones with frozen hearts. Mathias, a career assassin, isn't a man to give in to emotion. Feelings are messy, and a smart guy would run away. But that won't get the job done. He needs to get closer. Needs...her? Blake knows she shouldn't get involved with a client, but she's lonely, it's Christmas, and when he smiles a certain way, she throws caution to the wind.
