Beneath The Mantle - Tapa blanda

Stuart Holmes is a travel blogger from Canada on his way to Antarctica. When his ship gets trapped in ice and buried by a mysterious fog, he and several others hike to a nearby island to radio for help. They never make it. Instead the four of them flee the murderous ice and descend into a deep cave where they discover an entire new world, replete with strange statutes, abandoned cities, man-eating plants, giant terrestrial birds, foreboding monoliths, and brutal mega-fauna long since extinct on the surface of the Earth. Beneath the Mantle is a fast-paced tale of subterranean worlds, hidden mysteries, and epic adventure.
