A small band of humans has just driven out the reptilian invaders they call dragons. They have wiped out the time travellers’ home base in the era before man walked the earth. They have ensured their own freedom – now they must fight for the survival of all humanity. The mission: to follow the dragons to wherever they have wandered to in time and destroy them. The force: a small army of Nomads and former slaves with a stolen time-transporter. The stakes: the once and future dominationof the earth.
