Earl Dumarest was on his way back to his home world - the mythical homeland of cosmic humanity he called Earth. Gradually, dangerously, he had picked up clue after clue to its galactic whereabouts as his quest moved outward from the crowded center of the Milky Way.
In the course of his desperate trek he had learned the one secret that the far-flung cyborg cult of The Cyclan required to assure their control over the thousands of inhabited spheres.
Always the Cyclan pursued, plotted, searched. Always Dumarest managed to slip past their clutches - until he found himself obligated to Zenya of Paiyar and forced to lead an army for her faction - while the Cyclan used the time to weave its web around him tighter and tighter.
