Deep beneath the Ural Mountains, in an underground city carved out by slave labor during the darkest hours of the Cold War, ancient caverns hold exotic and dangerous life-forms that have evolved in isolation for countless millennia. Cut off from the surface world, an entire ecosystem of bizarre subterranean species has suvived undetected--until now.
Biologists Nell and Geoffrey Binswanger barely survived a previous encounter with terrifying, invasive creatures that threatened to engulf the Earth. They think the danger is over--until a ruthless Russian tycoon lures them to his underground metropolis, where they find themselves confronted by a vicious menagerie of biological horrors. Rising from the bowels of the Earth, these creatures now threaten to conquer the world. And if any reach the surface, they will succeed.
