He was a survivor - a wanderer who traded tales for food and shelter in the dark and savage aftermath of a devastating war. Fate touches him one chill winter’s day when he borrows the jacket of a long-dead postal worker to protect himself from the cold. The old, worn uniform still has power as a symbol of hope, and with it he begins to weave his greatest tale, of a nation on the road to recovery. This is the story of a lie that became the most powerful kind of truth.

An unabridged audio collection of the best-of-the-best science fiction stories published in 2015 by current and emerging masters of the genre, edited by Allan Kaster, as narrated by top voice talents.

For nearly a billion years, every known sentient species in the universe has been the result of genetic and cultural guidance - or "uplifting" - by a previously uplifted patron race. Then humans are discovered. Having already uplifted chimps and dolphins, humanity clearly qualifies as an intelligent species, but did they actually evolve their own intelligence, or did some mysterious patron race begin the process, then suddenly abandon Earth?

Historians have long studied how civilizations rise and fall. But today it isn't just social collapse that makes thoughtful people fret but a potential end to everything. From nuclear war to ecological disaster to rocks from the sky all the way to luring unfriendly interest from "others" out there, science has shed light on myriad ways to fail. To tumble back down into entropy. So, want to have some fun listing and weighing all the ways (that we know) the universe could have it in for us?

Prescient and scientifically accurate, Heart of the Comet is known as one of the great hard SF novels of the 1980s. First published in 1986, it tells the story of an ambitious manned mission to visit Halley's Comet, alter its orbit, and mine it for resources. But all too soon, native cells - that might once have brought life to Earth - begin colonizing the colonists. As factions battle over the comet's future - and that of Earth - only love, courage, and ingenuity can avert disaster and spark a new human destiny.

Technology has given average humans far more health and wealth and freedom of action than ever. New gifts spill forth at an accelerating pace as the sheer amount that we know rockets beyond our ability to process. This acceleration has some pondering a looming singularity - an approaching time of transition, spurred in part by new kinds of artificial intelligence - that could make the year 2050 as strange to us as a cave dweller would find our modern cities. Are these extrapolations well based?

Let's zoom in to the Internet, that magnificent new world for latter-day explorers, so much more vast than any realm discovered by Columbus or Magellan. Zealous enthusiasts point to how much more knowledge the average person can access, predicting better students, better workers, better minds and citizenship. Pessimists perceive a dumbing down that spread users too thin, resulting in shallowness that could be lethal to politics, to clear thinking. Is Google making us stupid? Let's weigh the evidence.

Today, a fresh crop of true believers, including brilliant scientists, view death itself as a problem to be solved. Are they fantasizing? What are the prospects and problems and unforeseen side effects of longer life spans?

Surveillance. It is used by every tyranny to lock in place an uneven arrangement of power. When the mighty know all about you but common folk know little in reverse, then without accountability you can only have despotism, as shown by 6,000 years of recorded history. But new technologies do not have to lock in perpetual Big Brother. The spread of tools like cheap cameras and instant sharing might lead to the antidote against Big Brother. That is, if we learn the lessons taught by both history and science.
