For centuries the Isher Dynasty has ruled a huge empire that includes earth and other planets. The Dynasty's power is checked only by the Weapon Makers, a group of dedicated scientists who prevent total take-over, who provide checks and balances to the Dynasty's political establishment. Now, for the first time in history, there is a spy among the Weapon Makers. He is in the confidence of the young Empress. So why is it the Empress herself who insists that he be killed? Why has she conceived this passionate hatred of Captain Hedrock? Suddenly the brilliant captain is hunted by both powers...and not even his incredible talent for survival is likely to help.
