Mankind once ruled planet Earth, smugly ignoring the tiny creatures crawling underfoot. Then came the cosmic catastrophe which put man at the mercy of the giant spiders, icily intelligent conquerors armed with awesome mind powers. It's their planet now -- but even they fear the Delta.

Somewhere in the Delta's hundreds of square miles of jungle and swamp, a power exists that could free mankind from its merciless eight-legged masters. Psionic rebel Niall and his band of adventurers seek the mysterious force deep within a green hell where evolution runs wild. . . a forbidden zone of man-eating plants, vampiric forests, murderous man-frogs, and 200-yard-long centipedes. . . a cosmic arena where an ancient godlike being holds the secrets of Creation.
