The U.S. Marine Corps made a man out of Nathan Morningway. But the orphaned baby girl left to him by his military buddy made him a father. A single father. With no training in diaper duty, let alone parenthood, Nathan heads home to Morningway Lodge––where he's not exactly warmly welcomed by his family. But day–care worker Jessica Sabin helps care for little Gracie and teaches him how to be a daddy. That seems to make Jessica happy. So why does she look so sad sometimes? Nathan's new mission: to find out––and make Jessica smile forever.
