Time Hideout

A catastrophe in the past nearly wiped out the human race. Those who survived became a part of a dictatorial society. Stark Ramsey is a rebel, known as an agitator, trying to oust a tyrannical potentate. The potentate lives in a luxurious palace behind a wall with all the amenities such as electricity, robot servants, and an air force. His constituents are peasant farmers who live outside the wall in a village of huts one would expect to find in the sixteenth century, not the twenty-fifth.
The agitators live in a fortress with obsolete equipment and weapons appropriated by whatever means available. When the potentate destroys the agitators' primary defense system, Stark has to sneak into the palace and steal repair parts.  His friend Chad is attempting to create a force field designed to cloak a person, and he needs parts, too.  With use of a part Stark brings back, Chad accidentally creates a time machine.
As war escalates, Stark goes back into the past to alter the future, but the past has a few surprises of its own and is not so easy to change. Stark finds hope in the arms of a woman who's everything he could want and more. Will he find love, or will he doom the future?
