To save a sick, orphaned boy, Anna Freeman must risk her own life. Little Paulo desperately needs a new heart. It's his only Christmas wish---well, that and building his first snowman. For the surgery, Anna must take him to a hospital in the city she once called home. A place she fled in fear years ago. Which means telling Dr. Lucas Bennett that the woman he's known all this time as a caring orphanage worker is really someone else. Someone with a very frightening past. And that the danger stalking all of them won't take Christmas Day off.
