When a group of children receives golden invitations to spend Christmas Eve in an ancient castle, excitement fills the air. Promised games, gifts, and a feast beyond imagination, they eagerly arrive-only to discover that the castle holds more secrets than holiday cheer.

As the night unfolds, strange events begin to test their bravery and their bond. Hidden rooms, flickering lights, and whispers of an old legend push the children to work together if they hope to make it through until morning. Along the way, they uncover the magic of true friendship, the power of kindness, and the meaning of giving without expecting anything in return.

When Santa Claus himself appears, the children learn that sometimes, the greatest gifts aren't found under a tree-they're found within the hearts of those who stand beside you.

Full of mystery, wonder, and heartwarming holiday spirit, Tag You're It Santa is a Christmas adventure readers young and old will never forget.
