A doctor with a guarded heart takes a chance on love and family with a beautiful nurse and her young son in this holiday medical romance. Single mom Louisa Austin's young son, Tyler, has Asperger's syndrome, and ever since the day her ex-husband bailed out on the both of them, she's vowed never to risk Tyler's happiness again. Brooding emergency physician Dominic Hurst doesn't do relationships—not anymore. But he's drawn to courageous nurse Louisa, and when her son starts riding at his stables, Dom forms a heartwarming bond with the troubled little boy. If the good doctor can put his heartache behind him and get down on one knee, he'll bring a Christmas miracle to this nurse-in-a-million and to a little boy in need of a friend—and a father.
