    The World Government calls upon him for aid in protecting an alien diplomat from a powerful and hostile member of his own species. Knowing both the importance of the task and his inability to handle it on his own, Singer goes to confront his greatest conquest with a strange bargain. A shape-shifting alien, the last of his species, sits in a special cage at an institute dedicated to the study of extraterrestrial beings. Most frequently he projects the aspect of a one-eyed catlike creature, but he can appear as almost anything.One of Singer’s secrets, and his greatest guilt, is his suspicion that the creature is intelligent. He confronts him and offers his own life for Cat’s cooperation in saving the alien. Cat accepts, and later, their mission fulfilled, demands a refinement on the original bargain.

As he uses matter transmitters to flit from Paris to London to the Middle East to the American Southwest, he must search back into his own early life as well as the root beliefs of his vanished people and come to terms with a world that has adopted him, made use of his skills, and left him feeling that he has no place to call his own.

    But there was something ... different ... about Santaroga.Santaroga had no juvenile delinquency, or any crime at all. Outsiders found no house for sale or rent in this valley, and no one ever moved out. No one bought cigarettes in Santaroga. No cheese, wine, beer or produce from outside the valley could be sold there. The list went on and on and grew stranger and stranger.Maybe Santaroga was the last outpost of American individualism. Maybe they were just a bunch of religious kooks...Or maybe there was something extraordinary at work in Santaroga. Something far more disturbing than anyone could imagine.

    The age of star formation is long past. Yet there is life here, feeding off the energies of the stellar remnants, and there is mind, a tremendous galaxy-spanning intelligence each of whose thoughts lasts a hundred thousand years. And this mind cradles memories of a long-gone age when a more compact universe was full of light... The 27th century: Proxima Centauri, an undistinguished red dwarf star, is the nearest star to our sun. How would it be to live on such a world?

    They called him Charlie. He had big eyes, abundant body hair and fairly long nostrils. His skeletal body was found clad in a bright red spacesuit, hidden in a rocky grave. They didn't know who he was, how he got there, or what had killed him. All they knew was that his corpse was 50,000 years old; and that meant that this man had somehow lived long before he ever could have existed!

    But now, they have emerged to ravage the land. Reissue.

Over the past two centuries, mankind has tamed its basest instincts, and reached the stars…But suppose it hadn’t happened that way at all? Suppose instead humanity’s darkest impulses, its most savage, animalistic desires had triumphed? Suppose that the empire mankind made out in the stars was one ruled by terror, where only those willing to brutalize their own kind and their neighbors could survive?One hundred years ago, four crewmembers of the U.S.S. Enterprise crossed the dimensional barrier and found just such an empire. A mirror image of their own universe, populated by nightmare duplicates of their shipmates. Barely able to escape with their lives, they returned thankful that the accident that brought them there could not be duplicated. Or so they thought.But now the scientists of that empire have found a doorway into our universe. Thier plan: to destroy from within, to replace one of our starships with one of theirs.
