The Schoolchildren's Blizzard

When nine-year-old Sarah and her little sister, Annie, set out on their way to school on January 12, 1888, they have no idea what their day will hold. The weather's so warm they go outside to play. Suddenly, the wind turns cold and begins to roar--it's a blizzard! The wind is so strong it rips the school's roof off. What will they do? The freezing snow is already up to their knees and without a roof they'll freeze. Their teacher, Miss Freeman, ties them all together with a long rope and they head out into the blinding storm. Will they make it to safety in time?
