Deep beneath the icy surface of Antarctica, a huge underground labyrinth has been discovered. In one of its caves, the remains of an ancient settlement were found that arose about five million years ago, that is, even before the appearance of the earliest human ancestors. Who lived here in those ancient times? A team of anthropologists must descend to the center of the Earth to solve this mystery and at the same time find out the origin of a figurine carved from a single diamond found in an underground village. But dark tunnels, caves and underground rivers hide not only this secret. Scientists quickly begin to realize that they are not alone in this mysterious labyrinth. A new super bestseller, new exciting adventures from the author of “Pyramid”, “Amazonia” and “Sand Devil”.
