Mike Sterne was a man with problems. His environment included an unknown quantity in the form of an eccentric alien scientist and a determined corps of totalitarian militia with orders to liquidate him.
A rigidly imposed authoritarian social structure can only be undermined by a superior ideology. Sterne encountered that ideology on the other side of an electronic gateway through the X dimensions, a gateway to the infinite universe of the microcosm and the macrocosm.
His enemies also discovered a route through the continuum... but they didn't reach the same world that Sterne had found.
