In a futuristic military adventure a recruit goes through the roughest boot camp in the universe and into battle with the Terran Mobile Infantry in what historians would come to call the First Interstellar War
This is the epic saga of an earthling, Valentine Michael Smith, born and educated on Mars, who arrives on our planet with "psi" powers--telepathy, clairvoyance, telekinesis, and the ability to take control of the minds of others--and yet with complete innocence regarding the mores of man.
Earth was being invaded by aliens and the top security agencies were helpless: the aliens were controlling the mind of every person they encountered. So it was up to Sam Cavanaugh, secret agent for a powerful and deadly spy network, to find a way to stop them--which meant he had to be invaded himself!
