Flung across space and time by the sorcery of super-science, John Gordon exchanges bodies with Zarth Arn, Prince of the Mid-Galactic Empire 2000 centuries in the future!
Suddenly John is thrust into a last-ditch battle between the democratic Empire World and the tyranny of the Black Cloud regime. Only one weapon—the terrifying Disruptor—can win the struggle for the Empire Forces. But it is so powerful that unless John uses it correctly it could destroy not only the enemy but the cosmos.

They were the Legion, the small body of fighting men that had been chosen to defend the new democracy after the overthrow of the despotic interplanetary Empire.
Now, in the 30th century, an alien solar system is about to invade the human planets and the golden age ends abruptly in an outbreak of terror, suffering, and—worst of all—deadly treason that has allied itself with the dreaded monsters of Barnard’s Planet.

To succeed, they will have to brave the dangers of the sinister Medusa World, the black spider-ship, and the Belt of Peril where death and madness lurk.
