A hidden door leading to a dark cave, a mysterious puzzle with 24 pieces turning into an exciting Advent Calendar Book!
Sam knows very well that it is not allowed to enter the library. He plucks up the courage and sneaks in. He runs his fingers over some of the books and accidentally opens a hidden door that leads down to a dark cave. In the cave he finds a mysterious puzzle with 24 numbers glittering with gold. Suddenly, nothing is the same. In what time period has he actually ended up? Who are the boys he ends up making a pact with and who is the mysterious girl from the shipwreck?
