Islands in the Sky - Michel Savage - Bog

At the edge of the world, an impossible relic from the fables of antiquity has risen from the frozen wastelands of Antarctica. Professor Logan and his exploration team rush to investigate this historic find, but this unique discovery puts their lives in peril when they unearth the remnants of a long-forgotten civilization left buried beneath the ice. Within the twisting labyrinths below the melting glaciers, they uncover an ancient culture that had perished from a mysterious cataclysm. They soon realize it was a polar shift which had caused their destruction, and our world was presently facing the same fate that could hurl our modern world back into the Dark Ages.
