This Christmas, siblings discover that every gift comes with a puzzle! Grandma and Grandpa have given mirror ciphers that must be solved before each present can be opened.
From baking cookies to building a snowman every clue unlocks a new holiday adventure. But the best surprise waits at the very end!
In each adventure, kids not only join the treasure hunt, but also learn fun new skills-like cracking secret codes or reading maps-that they can
use in their own quests!
