For three years, the memory of Sarah Kirkman's dead husband has kept other men at bay. Her heart only has room for her six-year-old daughter, Melinda. On a vacation to the Smithsonian, the Kirkmans run into Doctor Duncan MacPherson, a paleontologist who befriends her dinosaur-obsessed daughter. Sarah's attraction to Duncan is undeniable but pointless--he must leave for his home in Scotland the very next morning. But Sarah has forgotten one important thing: Christmas really is for miracles.
