After laboring for thousands of years, the people of Earth, fleeing ecological disaster, have built a new, clean, stable world on a worldwide platform erected over the entire land surface of the Earth. Everything is going well--except for Carl Magner, the man who's been having bad dreams. He shouldn't be having dreams at all, because dreams have been banished from the society of the Euchronian Millennium, but somehow he is, and his dreams are showing him the "Underworld." The real surface of the Earth, the Underworld that the Euchronian Millennium has left behind, still maintains life, human and otherwise, life that's adapted to a world without sky or sun, still evolving in response to extreme environmental challenges. Dreams are only dreams, but they're a provocation nevertheless, not merely for Carl Magner, but for the whole of Euchronian society. Can Heaven be truly Heaven, if Hell still festers in its entrails?

Subterranean Realms is a unique book that surveys underground and rock cut structures created in the past. It is the third book in Mutton’s trilogy on mysterious realms, the others being Sunken Realms and Water Realms. We know who built some of these astonishing and mysterious structures, but others were built by unknown civilizations in prehistory for reasons that are debated among researchers. Some subterranean structures may have been built for initiation ceremonies or perhaps for acoustic reasons, or both. Mutton discusses such interesting sites as: Derinkuyu, an underground city in Cappadocia, Turkey that housed 20,000 people; Roman catacombs of Domitilla; Palermo Capuchin catacombs; Alexandria catacombs; Paris catacombs; Maltese hypogeum; Rock-cut structures of Petra; Treasury of Atreus, Mycenae; Elephanta Caves, India; Lalibela, Ethiopia; Tarquinia Etruscan necropolis; Hallstatt salt mine; Beijing air raid shelters; Japanese high command Okinawa tunnels; more. There are tons of illustrations in this fascinating book!

The masters of the Euchronian Millennium are panicking. The fabric of their ideal society on the platform built over the Earth has been ripped, and the order that they hold so precious seems to be teetering on the brink of collapse. In order to save it, the Hegemon has decided to obliterate all life in the perpetually covered Underworld of Earth from which the threat comes--but his followers are of two minds as to whether that's even possible, let alone justifiable. As the opposition grows, the plan goes forward--but then the Underworld begins to fight back, and everything's thrown into chaos: a chaos with which the citizens of a supposedly ideal society are simply not equipped to deal. Meanwhile, in the Underworld, the fight for survival goes on, as bitterly and ruthlessly as ever. The smashing conclusion to The Realms of Tartarus Trilogy!

The people of the Euchronian Millennium had been reminded of the Underworld that existed beneath the platform on which they had constructed their better, cleaner, safer world--leaving the original surface of Earth a dark, dreary, and forgotten place. That awareness had become a political pawn, which many different people were trying to manipulate in their own interests. In the meantime, the search for more information about what actually existed in the Underworld went on, tentatively and ineptly. The hunter sent to help clarify the situation brought back a sensational prize, and revealed it to the world--but in so doing, he triggered an unexpected and unprecedented reaction, which changed the whole nature of the game, gave the people of Heaven a vision of Hell, and threw the fate of both worlds into the balance. The second novel in the exciting Realms of Tartarus series!
