The knoll should have been nothing. A bump in the Kansas wheat fields, barely worth noting. But when Perry Wilcox and Dr. Roderick Murgatroyd start drilling, they break through into a world that shouldn't exist. Beneath the earth lies a fortress from a civilization that died millions of years ago, its corridors still humming with power, its robotic guardians still marching in silent, endless patrols. The machines were built for war, and war is what they'll get. What begins as a scientific marvel becomes a nightmare when the military arrives and opens fire on the mechanical sentinels. In the chaos, Wilcox and Murgatroyd are shrunk to miniature size, trapped in a hidden world of towering corridors and deadly automatons. They'll need to uncover the secrets of this ancient race before the robots finish what they started and the technology falls into the wrong hands. This is 1940s pulp science fiction at its finest: wide-eyed, propulsive, and full of the kind of wonder that comes from stumbling into the impossible.
