Ryland Grace is the sole survivor on a desperate, last-chance mission - and if he fails, humanity and the Earth itself will perish. Except that right now, he doesn't know that. He can't even remember his own name, let alone the nature of his assignment or how to complete it. All he knows is that he's been asleep for a very, very long time. And he's just been awakened to find himself millions of miles from home, with nothing but two corpses for company.

Bob Johansson didn't believe in an afterlife, so waking up after being killed in a car accident was a shock. To add to the surprise, he is now a sentient computer and the controlling intelligence for a Von Neumann probe. Bob and his copies have been spreading out from Earth for 40 years now, looking for habitable planets. But that's the only part of the plan that's still in one piece.

The Yellowstone super-eruption has put an end to modern civilization. As cities and countries continue to fall, the colony of Rivendell in the alternate Earth known as Outland looks more and more like the only real hope for humanity. But life in Rivendell isn’t getting any simpler, either. Bill and Kevin continue to discover new worlds; the population continues to rise; winter is approaching; and everyone has their own opinion about how things should be run.

When an experiment to study quantum uncertainty goes spectacularly wrong, physics student Bill Rustad and his friends find that they have accidentally created an inter-dimensional portal. They connect to Outland - an alternate Earth with identical geology, but where humans never evolved. The group races to establish control of the portal before the government, the military, or evildoers can take it away. Then everything changes when the Yellowstone supervolcano erupts in an explosion large enough to destroy civilization and kill half the planet.

Few know the warship’s actual name. But everyone has heard the rumors. The PUV James Keeling can do something no other vessel in existence can do—slip into another dimension, travel undetected, then re-emerge onto our plane and surprise enemy targets. But the thing that makes the Crypt unique also makes it a nightmare for those onboard; interdimensional travel causes hallucinations, violent behavior, and psychotic breakdowns. Keeling could be the Union’s greatest weapon, a game-changing asset that can defeat the bloodthirsty zealots of the Purist Nation, the Union’s mortal enemy.

Paleontologists say 99% of all species that have ever lived on Earth are now extinct. Extinction is natural—until it isn’t. Paleontologists have declared we are living through the Sixth Mass Extinction, a human-triggered crisis unfolding not over millions of years, but within decades. From climate collapse and ecological ruin to the looming threat of nuclear war, the timeline to disaster is no longer hypothetical—it’s accelerating.

The master of science-fiction is back for Volume Two of the Ray Bradbury Classics Collection. These legendary tales come straight from the Golden Age of Sci-Fi, and are just as intense, dark, and full of flavor as the stories in Volume One. Buckle up your space seatbelt, and let’s take a journey across hostile worlds in Asleep in Armageddon, encounter mystery and danger in Lorelei of the Red Mist, explore the consequences of creation in The Monster Maker, and discover the wit, imagination, and humanity that would later make Bradbury one of the most celebrated authors of the twentieth century.

In Echoes of Humanity, Dr. Ethan Graves, a renowned surgeon facing terminal cancer, embarks on a groundbreaking journey to preserve his memories and consciousness through Neuralink technology. As he grapples with the ethical and emotional weight of becoming a humanoid robot, Ethan confronts questions of identity, mortality, and what it means to be truly human.

A week ago, the supernova Aeon detonated in the skies over Antarctica. Mass migrations of humanity and animal life began northward. Secondary bursts of ionizing radiation knocked out worldwide power grids. Global temperatures spiked. Oceans rose as seawater expanded and glaciers melted. Massive storms and acid rain scour the planet. The southern continent is literally melting under the feet of Dr. Xin Rhou as she is trapped at the South Pole, and she is perhaps the only person in the world with a full accounting of the data recorded when Aeon exploded.

The Terran Union is engaged in a vast interstellar war against the Krag Ruthless aliens intent on exterminating humankind.

Robichaux’s first mission: to take his warship to the Free Corridor, where the Krag have secretly been buying strategic materials, and to seize or destroy any ships carrying enemy cargo.

Story three of The Dawn series follows Victor Siversky, a talented, outspoken scientist researching the biological foundations of human moral judgment.

When it comes to artificial intelligence, we’re no longer in a “what if?” reality. We’re squarely in a “now what?” world. From books to financial markets, from healthcare to research, the age of artificial intelligence has arrived. We’re in for a ride, and it’s anything but smooth. What will the world look like as we share it with the genie we let out of its digital bottle? How will AI evolve? Perhaps, even more important, how will we?

The atomic mushroom clouds over the Mediterranean have dispersed, and now, as the world teeters on the brink of a new thermonuclear war, it is dawning on the "victors" that their "victory", far from being absolute, was tragically pyrrhic. In the uneasy half-peace, the United States stirs from its post-Cuban Missiles War slumber. But will it awaken soon enough to overcome its own divisions to confront the new and terrible forces unleashed by Red Dawn's first paroxysm of violence?

Morgue Ship by Ray Bradbury is a science fiction short story, which appeared in the summer 1944 issue of Planet Stories and is therefore eligible for the 1945 Retro Hugos. Morgue Ship is short, only six pages long, but Bradbury perfectly manages to capture the atmosphere aboard the morgue ship with its clinical interior, its shelves full of dead soldiers, the churning blood pumps and whirring machinery, in such a short space. Bradbury also manages to pack the horrors of war in space, the exploding ships and spinning dead bodies among the wreckage, into just a few paragraphs.
