Price I paid: none
What would happen if man’s mastery of the world was suddenly snatched away by a new and more advanced type of life? This is the startling premise of this unusual novel.
It fell to two people to face the news that mankind was about to follow the dinosaurs off the Earth’s stage. One was Angus, veteran of a defeated Western army in a world devastated by atomic warfare. The other was Liu, woman officer of a conquering army she already knew was destined for destruction.
How these two found the new master species and what they did about it is an exciting and thought-provoking science-fiction adventure.
