The Carpathian Riddle - The Dacian Cipher #1018495

***The Carpathian Riddle - Book 2 ***

The detox is over. The real hunting begins.
Two months after escaping the Retezat mine, Alex, Victor, Maya, and Lara thought the danger was behind them. They were wrong.
 
When Victor discovers micro-engraved GPS coordinates hidden inside the lid of his grandfather's brass compass, they point to one of Romania's most restricted sites: the ancient Dacian royal capital of Sarmizegetusa Regia. Before the group can act, Victor's father — a historian who has been following the same trail — vanishes. His last words, crackled through a failing phone signal: "They found the alignment. Don't trust the camp files—"
 
The call cuts off with the sound of breaking glass.
Armed with a drone running custom offline software, a decoded notation system, and Maya's photographic memory cross-referencing a two-thousand-year-old cipher, the four friends descend into the mountain — and into something far larger than a criminal mining operation.

The Iron Grid isn't just after coltan. They're after the Dacian Cipher: a rotating stone mechanism that guards the most significant undocumented archaeological site in Romanian history, protecting a mineral cluster the organisation has spent twenty years trying to reach. A mineral cluster that, in the wrong hands, could break every encryption system on Earth. Simultaneously.
 
The Carpathian Riddle: The Dacian Cipher is a fast-paced middle grade adventure thriller, packed with real Dacian history, underground tension, tactical drone sequences, and a technology-vs-ancient-engineering puzzle that keeps the stakes climbing all the way to the final page.
 
The grid is not complete. The third layer is waiting. And the Genesis Protocol has already started counting down.
