THE THREE STIGMATA HAD A SECRET THAT COULD TRANSFORM THE WORLD OR END IT. ..
When the mysterious Palmer Eldritch returned from a distant galaxy, he claimed to have brought a gift for mankind. Chew-Z was a drug capable of transporting people into an illusory world, a world they could linger in for years without losing a second of Earth time. For the lonely colonists living out their dreary term on Mars, here was the ultimate trip, a pastime that could deliver immortality, wish fulfillment. . . the twin-power over time and space. But in return, Palmer Eldritch exacted a terrible price. He would enter, control and be a god in everyone's private universe - a universe from which there was no escape, not even death. . .
