Admiral Mordrax, the Hyron commander whose bloodlust has pursued Richard Cameron and the Space Star Silver Streak across the galaxy for thirteen years, returns with an awesome new warship to finally destroy his old enemy!

In this, the biggest, most awe-inspiring Voyage Into the Unknown adventure ever, the Silver Streak is brought to the brink of destruction! When the bridge is shattered, Richard Cameron, Frank Johnson, Jack Hasta, and Philippe Stargazer awaken...a thousand years later!

Trapped aboard a battered remnant of the Silver Streak which is disintegrating around them, the old friends must work with their own descendants to try to find a way home--even if it means killing their daughters in the process!
