**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 13+.**

*I loved that it was super exciting but also funny at times — and even a bit romantic. It had everything I want in a story!*
— *A Girl, Age 13*

A modern, page-turning adventure even reluctant readers will tear through, packed with everything young readers love: a quantum tablet with an artificial intelligence, immortal knights, a powerful artifact from biblical times, a leap into a digital universe, first crushes, puzzles that need solving, and plenty of humor. Our teenage hero is smack in the middle of puberty.

## The Author

![Karim Pieritz](https://www.kaspabue.de/wp-content/uploads/2017/06/Karim_Pieritz-200x300.webp)

Karim Pieritz, a German author from Berlin, began spinning tales when his son begged for “just one more” bedtime story. Those late-night ideas grew into the **[Lighthouse of Adventure](https://www.kaspabue.de/en/lighthouse-of-adventure-trilogy/)** trilogy—fast-paced, playful fantasy for children.

As his son grew older and asked for something bolder, he wrote his first young adult adventure novel, **[The Hunt for the Mysterious Cylinder Seal](https://www.kaspabue.de/en/the-hunt-for-the-mysterious-cylinder-seal/)**.

Continuing to craft immersive worlds for older readers, he expanded his young adult catalog with **[Guardians of the Soulwood](https://www.kaspabue.de/en/guardians-of-the-soulwood/)**, a captivating fantasy novel for ages 13 and up.
