(From the publisher):
The aliens came from a distant star - and a distant time. People of the future, they couldn't be destroyed in the present. The only hope of conquering them was by traveling forward in time. So one brave man set off on his dangerous mission into another age, with one great question in his mind. Even if he could find the right time zone, could he destroy the aliens? Could the future be changed?
