There’s no end to the mysteries of the underground world. What does a person look for in that mysterious—but far from fairy-tale—world that is, more than anything, full of dangers? What attracts them to the dark, almost unknown interior of the Earth? Is it its similarity to their own soul?
The underground world is terra incognita (unknown land). It’s studied by fearless pioneers and specialists in their fields—travelers, geologists, archaeologists, speleologists, biologists, historians. This world holds a lot of the unexplored and the unclear. It is a kingdom of silence and darkness that lives its own life. A story about the most interesting discoveries by scientists awaits you in this audiobook.
