At the top of the Big Tree lives a family of squirrels - father, mother and three baby squirrels - Melchior, Baltazar and Caspar (these were the names of the wise men who brought gifts to Jesus for Christmas). On the eve of the great holiday, Luke Caspar went somewhere and disappeared, so dad goes in search. Together with him, little readers will jump from branch to branch, look for animals and chicks, open bright windows with surprises to finally find out where the elk, the squirrel and his friends are hiding, and how they are preparing for Christmas in this magical forest.
