Twenty-four miniature board books are nestled into 24 windows, numbered 1 through 24 &, like the peek-a-boo windows of an Advent calendar, are meant to be opened one-per-day from December 1 through Christmas Eve. Read in sequence, night after night, the full-colour four-page books & capture the magic of Marie`s Christmas Eve adventures, from the entrance of the mysterious Herr Drosselmeyer (Book 6) to the Nutcracker`s battle with the Mouse King (Book 15), to a thrilling celebration at the palace of the Sugar Plum Fairy (Book 19). In addition, children can use the vividly illustrated books-with gold thread loops & four different trim sizes---to hang on the family Christmas tree.
