"In an old house in Paris that was covered with vines lived 12 little girls in two straight lines." So begins this delightful story of Madeline's Christmas! The day begins like any other day. Miss Clavel takes the 12 little girls on their morning walk. They go to the zoo and then back to school for their French history lesson. Suddenly, disaster strikes when everyone gets the flu! Everyone, that is, except for the ever-resilient Madeline. Saddened that they may not be able to go home for Christmas, the girls and Miss Clavel take to their beds. But on Christmas Eve, the adventure begins when there is a knock at the front door.
