The Hunt for the Mysterious Cylinder Seal

What would you do if your parents dumped you at a boarding school with no cash and no phone? John is furious that the class group chat won‘t stop posting dumb stuff about him. When his parents catch wind of it, they freak out and ship him off to a boarding school in a forest in the middle of nowhere. The medieval-style castle has zero cell reception or Wi-Fi, and his parents actually think that‘s a good thing. One night, following eerie sounds through the castle, John meets the beautiful Charlotte. Something has happened to her, and she doesn‘t have long. A mysterious cylinder seal might save her, but to find it he has to crack tough riddles and face dangers that once sent the ancient Romans running. Get ready for a high-stakes adventure with absurdly funny midnight dance rituals and classmates you‘d better avoid when the full moon rises. Join John on a rescue mission that races from stalactite caves to a digital universe, where more than one girl manages to turn his head. Book 1 of the YA Series for readers ages 12 and up. English edition of "Die Jagd nach dem geheimnisvollen Rollsiegel".
