Possessing extraordinary powers, including the ability to bring artwork to life, twelve-year-old twins Matt and Emily are sought by villains trying to access the terrors of Hollow Earth, a place where demons and mythological beasts lie trapped for eternity.

1964 Dr. Bernard says this is the true home of the flying saucers. the epoch-making significance of Adm. Byrd's flight for 1,700 miles into the North Polar opening leading to the hollow interior of the earth, the home of a Super Race who are the Creators.

Beliefs in mysterious underworlds are as old as humanity. But the idea that the earth has a hollow interior was first proposed as a scientific theory in 1691 by Sir Edmond Halley (of comet fame), who suggested that there might be life down there as well. Hollow Earth traces the surprising, marvelous, and just plain weird permutations his ideas have taken over the centuries. From science fiction to utopian societies and even religions, Hollow Earth travels through centuries and cultures, exploring how each era's relationship to the idea of a hollow earth mirrored its hopes, fears, and values. Illustrated with everything from seventeenth-century maps to 1950s pulp art to movie posters and more, Hollow Earth is for anyone interested in the history of strange ideas that just won't go away.

A gripping history of the polar continent, from the great discoveries of the nineteenth century to modern scientific breakthroughs Antarctica, the ice kingdom hosting the South Pole, looms large in the human imagination. The secrets of this vast frozen desert have long tempted explorers, but its brutal climate and glacial shores notoriously resist human intrusion. Land of Wondrous Cold tells a gripping story of the pioneering nineteenth-century voyages, when British, French, and American commanders raced to penetrate Antarctica’s glacial rim for unknown lands beyond. These intrepid Victorian explorers—James Ross, Dumont D’Urville, and Charles Wilkes—laid the foundation for our current understanding of Terra Australis Incognita. Today, the white continent poses new challenges, as scientists race to uncover Earth’s climate history, which is recorded in the south polar ice and ocean floor, and to monitor the increasing instability of the Antarctic ice cap, which threatens to inundate coastal cities worldwide. Interweaving the breakthrough research of the modern Ocean Drilling Program with the dramatic discovery tales of its Victorian forerunners, Gillen D’Arcy Wood describes Antarctica’s role in a planetary drama of plate tectonics, climate change, and species evolution stretching back more than thirty million years. An original, multifaceted portrait of the polar continent emerges, illuminating our profound connection to Antarctica in its past, present, and future incarnations. A deep-time history of monumental scale, Land of Wondrous Cold brings the remotest of worlds within close reach—an Antarctica vital to both planetary history and human fortunes.

Matt and Emily Calder’s travels through time come to a thrilling conclusion in the third book of the Hollow Earth trilogy as the siblings struggle to close Hollow Earth—and keep the monsters inside. Twins Matt and Emily Calder may be divided by time, but they are united in their mission to close Hollow Earth before the monsters inside can destroy the world. The key to success lies with their Animare talents: they can draw things into life and travel in time through art. But there are monsters outside Hollow Earth as well. Monsters intent on taking control of the beasts for themselves. And the worst monster of all is their own father…

One of the world's great mysteries is: do we live on a hollow earth? In the first detailed investigation of a legendary belief that can be traced back to the dawn of time, the bestselling author of The Lost World of Agharti examines the possibility of an inner world, a hollow Earth which could explain some of the greatest mysteries of our time. Was this hollow Earth inhabited before mankind set foot on the planet's surface? Did the people of Atlantis and Mu take refuge there when catastrophe overtook them? Do UFOs come, not from outer space, from inside our own Earth? Bringing together years of painstaking research, Alec Maclellan looks not only at the persistent historical tradition but at the work of great scientists such as Edmond Halley and Leonhard Euler, infamous figures such as Cotton Mather and Adolf Hitler, and extraordinary researchers, each of who has devised an explanation for the legend. There have been men who claimed to have visited the Hollow Earth and provided eye-witness accounts of their journeys. Most thought-provoking of all is the vast amount of scientific evidence in support of the Hollow Earth concept, including explorers' reports of polar entranceways backed up by remarkable satellite photographs and evidence from unmanned spacecraft that other planets in our solar system may be hollow too. With many rare photographs The Hollow Earth Enigma explains how this extraordinary legend has captivated our imagination and how, despite its dismissal by science, it is scientifically possible.

1983 Highly illustrated. Gives much valuable information on the hollow earth, hollow earth societies, early hollow earth pioneers or "In-Earthologists".
