It is the year 1925, and in the frontier town of Nome, Alaska, people were facing a diphtheria epidemic. Two children are very sick, and others could be soon. The nearest hospital was 700 miles away and the train bringing the medicine can’t get through the deep snow. Twenty-one dogsled teams would take turns carrying the medicine from Anchorage to Nome and the hero of all the dogs was Balto. Students love this book!
