An undercover Paratimer has disappeared on assignment while in an alternate time line, and it’s up to Verkan Vall of the Paratime Police to save her. To do so, he must infiltrate a universe in which assassination is an honorable profession, and reincarnation a scientific fact. Will Verkan Vall survive in a world of killers and the undead?

"There's some reaction these days that holds scientists responsible for war. Take it one step further: What happens if "book-learnin'" is held responsible ...?"

I'll bet you did not know that our little earth is not limited to the single time line on which we happen to exist. That's right; There are actually thousands, no many millions of parallel times, each existing alongside all the rest, using the same real estate, but following their own path. Some extremely primitive, some very advanced, but all blissfully unaware of the others. Of course this does not affect us at all, unless ... unless one of these time lines discovers the existence of the others and then a way to move easily back and forth from one to the other...

The Paratime Police had a real headache this time! Tracing one man in a population of millions is easy--compared to finding one gang hiding out on one of billions of probability lines!

Naudsonce? What does THAT mean? Well, to find out you will need to listen to this story where Piper's unique mind explores what we mean by 'communication' and how it happens. The joint Space Navy-Colonial Office expedition was looking for new planets suitable for colonization; they had been out, now, for four years, which was close to maximum for an exploring expedition. They had entered eleven systems, and made landings on eight planets. Three had been reasonably close to Terra-type but were all disqualified by terrible animals or warlike inhabitants...

But a mystery missile suddenly intercepts the probe and splashes it in the South Atlantic.Faced with a huge search task to find the probe on the ocean bottom, Tom soon realizes that the same shadowy group that attacked the probe is competing to find it, and no holds are barred: kidnap, coercion, and lethal force are all in play.Under such circumstances, what can Tom do? What he does every time, of course! He invents some utterly cool device to get the job done! And his Electronic Hydrolung is just the beginning!

Garrett Putnam Serviss (1851-1929) was an astronomer, popularizer of astronomy, and early science fiction writer. Serviss showed a talent for explaining scientific details in a way that made them clear to the ordinary reader. Serviss’s favorite topic was astronomy, as shown by the fact that of the fifteen books he wrote, eight are devoted to that science. He unquestionably was more widely read by the public on that topic than anyone prior to his time. In his private life Serviss was an enthusiastic mountain climber, describing his reaching the summit of the Matterhorn at the age of 43 as part of an effort “to get as far away from terrestrial gravity as possible...

Edison’s Conquest of Mars, by Garrett P. Serviss, is one of the many science fiction novels published in the nineteenth century. Although science fiction was not at the time thought of as a distinct literary genre, it was a very popular literary form, with almost every fiction magazine regularly publishing science fiction stories and novels. “Edison’s Conquest of Mars” was published in 1898 as an unauthorized sequel to H. G. Wells’s The War of the Worlds, but did not achieve the fame of its predecessor. The book was endorsed by Thomas Edison, the hero of the book — though not by Wells.

In desperation he turned toward Haney. “My God, we’ve been locked out!” Through the transparent domes of their space helmets, Joe could see a look of horror and disbelief pass across Haney’s face. But it was true! Joe and his crew were locked out of the Space Platform. Four thousand miles below circled the Earth. Under Joe’s feet rested the solid steel hull of his home in outer space.

It is 30,000 years following dramatically changed climate conditions on earth which had let massive amounts of carbon dioxide belch from the interior of the planet into the atmosphere. Over the millenia this would have quite devastating effects on life as it had once been known. Much of the human and animal population would not survive the climate change, and indeed those few humans who did survive knew nothing of all which their predecessors had learned and built. Indeed, they knew not even of their existence...
