From Hugo and Nebula Award-winning author Robert Silverberg comes, To Open The Sky. The Atom was their God-but there was something stronger... At the beginning of the 22nd century, Earth colonies were established on Mars and Venus. But the ultimate dream - to travel to the stars - was still an impossibility. Cults, fads, madnesses of various kinds swept the population. The maddest--and so far the most permanent--were the Vorst worshipers, the atom adorers, the believers in immortality through technology. Yet there were the Harmonists, who believed that technology could never do it. And the hatred between the two factions was too deep to be reconciled - until a conflict on Venus between a Vorster priest and his Harmonist opponent resulted in unexpected developments.

Caught in the midst of a rebellion while visiting a friend thousands of miles from home, Joseph, the young heir to the great House Keilloran, one of the Masters who colonized the planet long ago, finds himself fighting for survival in enemy territory, through which he must travel while facing terrible dangers.Robert Silverberg is a SFWA Grandmaster and winner of multiple Hugo and Nebula awards.
