A reading that leads to the Unknown. The in-depth sequel to the first best-selling book Hollow Earth.

Pantelis Giannoulakis' second book on the mystery of Hollow Earth has found its way to its readers. A semi-enlightened path, passing through labyrinthine underground passages, through strange caves, through ancient oracles and forgotten temples, through gates leading to other dimensions of existence, amidst shadows and mythical creatures, within hills, behind dark libraries, above dreams and visions, amidst monsters and angels, traversing a secret geography, to the center of the Earth, and from there to the depths of the human soul.
