(bound with) One Against Eternity, original title: The Weapon Makers. (Cover artist unknown - possibly Ed Valigursky for the style of buildings in the background?, 186 pages.)
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. Then why is it the Empress herself who insists that he be killed? Why has she conceived this passionate hatred of Captain Hedrock? Hunted as a traitor by both sides, haunted by terrible powers he dared not reveal, Captain Robert Hedrock was an outsider who could change the course of history. He was a man with no future and no past - his true identity a secret whose telling would be punished by sure death.
