It’s a typical holiday morning. No school, no plans. All your friends are abroad with their families, your sister Alice is on a road trip with her friends, your brother Alex is busy with his girlfriend, and your parents are relaxing together at home. And you? You did everything you wanted way too early when the holidays started. Now there’s nothing left to do. You’re completely bored.

But this morning isn’t as normal as it seems.

When you get out of bed and stretch your arms, you notice something strange on your left arm—a mysterious tattoo that definitely wasn’t there before.

You don’t know it yet, but this tattoo is about to change your life forever… if you manage to figure out how it works.

(What will you do?)
