A woman-dominated society, flying machines, robots, telephones, automatic household appliances, lasers - things that humanity had never even imagined - are all here. And all of these thanks to the infamous power of Vril, a power that the underground Race draws from the environment and directs with its trained, superhuman will. Many see Vril as modern nuclear energy, although it seems to resemble more the energy that Tesla was seeking.
In such a technologically and biologically advanced utopian society, the hero of this book is almost heavenly. Almost, because the heavenly country with its angelic inhabitants is located underground. And so the famous myth of the HOLLOW EARTH is revived in the most captivating way.
