Alvin Van Der Kuech

When a hunter sent back to the prehistoric era runs off the path he must not leave, he causes a chain reaction that alters history in disastrous ways.

In a lawless futuristic society, a rebel must prevent a tandem of renegades from destroying Los Angeles. An ex-star pilot is forced to stop a mad criminal and his gang after they've hi-jacked a huge space freighter with the intent of crashing it into Los Angeles destroying what is left of civilization. Time is running out.
