One April day when Lars is driving Kirsten's mother and aunt Inger to the store (and her father and uncle are still in the logging camp), a sudden blizzard blows in. Kirsten, Peter, Lisbeth, Anna, and Britta are safe in the cabin, but Kirsten's worried about her older brother, mother, and aunt. It's a fierce storm, and even opening the door for a moment to let the dog in results in snow blowing in to the extent that that they have to shovel it out of the way to close the door again. The house is so cold that they all decide to just go to bed early, with the bed shoved near the fireplace and piled high with blankets, and wearing their winter clothes.
The next morning, the sun is shining. But where's Britta? Kirsten is terrified that she might have frozen if she's been out from under the covers for too long. A frantic search ensues, and much to Kirsten's relief, the baby is sleeping soundly under the bed, with the dog curled up next to her, keeping her warm. The older children set about building up the fire, deciding what furniture might need to be burned if circumstances warrant it, and digging a path to the barn to tend the animals. In the middle of the last chore, they're delight to see Lars returning with the women, and supplies from the store. They've all made it through the blizzard safe!
The section this time details the blizzard of 1888. It's laid out like a newspaper with short articles about a vicious blizzard that sneaked up on an unseasonably warm day, causing a lot of death and destruction.
It amuses me to no end that this story has snowbound with an exclamation mark and the seventh Baby-sitters Club super special is titled Snowbound!
