The Lost Alpine Diary

Deep beneath the ice of the Alps, a secret has been waiting for centuries. When Lukas Keller discovers the final diary of his brother Matthias - a historian who vanished during a mysterious expedition - he follows the clues to a hidden chamber buried inside a glacier. What he finds there changes everything. Inside the ancient structure lies evidence of a global network older than recorded history, protected for centuries by a secret organization known as the Meridian Circle.
But the chamber is not a prison. It is a gateway. As Lukas, journalist Sienna Carter, and enigmatic researcher Klaus Reinhardt uncover the truth behind the ancient system, they realize the network was never meant to remain hidden forever. And somewhere beyond the portal, something has been waiting for humanity to open the door. Now the question is no longer whether the gateway should be opened.But whether it can ever be closed again.
Perfect for readers who enjoy fast-paced thrillers filled with ancient mysteries, secret societies, and world-changing discoveries.
