The Plasma Master 17

Nedward Simmons is living a regular Earth life when he stumbles across an artifact from an alien civilization. Its protective powers are more intriguing than useful to him, until the aliens themselves arrive. Unable to hand over the power he has unwittingly acquired, Ned decides instead to travel with them in an attempt to defeat the Anacron army, which threatens their freedom. But Ned soon learns that his Plasma Crystal is not the only source of mysterious power in the galaxy. Ned and his comrades must deal with a vast space armada, enemy Plasma Masters, and even a monster or two as they search for a way to penetrate the enemy fortress of Venom and restore peace to their empire.
