    But there was no radiation detected, and, when physicist Dr. William Weaver and Navy SEAL Command Master Chief Robert Miller were sent to investigate, they found that in the center of the destruction, where the University's physics department used to be, was an interdimensional gateway to . . . somewhere. An experiment in subatomic physics had produced a very unexpected effect. Furthermore, other gateways were appearing all over the world and one of them immediately began disgorging demonic visitors intent on annihilating all life on Earth and replacing it with their own. Other, apparently less hostile, aliens emerged from other gateways, and informed Weaver and Miller that the demonic invaders, the name for them that humans could most easily pronounce was the Dreen, were a deadly blight across the galaxy, occupying planet after planet after wiping out all native life; and now it would be Earth's turn, unless Weaver and Miller could find a way to close the gateways. If they failed, the less belligerent aliens would face the regrettable necessity of annihilating the entire Earth to save their own worlds. . . .

    Earth's inhabitants are unfazed as they believe him to be yet another doomsayer; the End of the Earth has been predicted for centuries. Jherek is far more interested in Mrs Amelia Underwood, a time traveller from Victorian England, as he is fascinated by the Victorian era. Jherek resolves to fall in love with her. Mrs Underwood, at first repulsed by the debauchery of the End of Time, finally comes to believe that Jherek is sincere in his affections and starts teaching him about moral values. She falls in love with him at last; as they are about to embrace, however, she is whisked back to her own time. Jherek, heartbroken, decides to rescue her, and travels to 19th century London.Jherek is inexperienced to the point of naivete about the Victorian Era, despite his interest in it, and a (temporally) local thief, Snoozer Vine, tricks him into becoming an accomplice to Snoozer's latest scam. Not surprisingly, Jherek proves to be a poor criminal, and is quickly arrested, jailed and sent to trial. To his surprise, the judge appears to be none other than his friend, Lord Jagged but claims to be one Jagger. Jherek is sentenced to death, as the case against him is unequivocal, but he cannot understand why all the people around him are so upset; inhabitants of the End of Time are immortal, and for them death is merely transitory. Jherek is hanged, only to wake up among his friends at the End of Time, who tell him that to them, he has only been gone for a second.This is the first Avon paperback printing.

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.

Their victims: the crew of the U.S.S. Enterprise NCC 1701-D.
