When the Germans mount an air attack on their quiet village, fourteen-year-old Agnes and nine-year-old Ollie are separated from the rest of their family as they are shuttled to supposed safety with a friend of their grandfather's. As weeks turn into months at a Red Cross refugee camp, the children wonder if they will ever see their mother, father, and grandfather again. But with Christmas coming, Agnes does her best to help Ollie hold on to hope—and soon, the two of them gain a deeper understanding of the meaning of Christmas.
