At long last, Earth has a handful of starships. Surrounded by Rebel Kher, Imperials, and the mysterious Nomads, humanity dares to assert our right to independence. The interstellar community reacts harshly. In the eyes of our neighbors, we’re upstarts, dangerous beings who don’t know our place. For the Kher, freedom can only be won through battle. War fleets arrive to instruct us, and Captain Leo Blake is again sent out to voyage among hostile stars.

Chronicler Tsai Yini monitors the tachyon communication system, which transmits data faster than the speed of light.

Their civilization is still in its infancy but revolves around an artifact of unknown origin that seems to influence their body chemistry.

With Louis’ help, the Hindmost intends to regain his status by bringing back such extraordinary treasures from the Ringworld that his fellow puppeteers will have to be impressed. But when they arrive, Louis discovers that the Ringworld is no longer stable - and will destroy itself within months. To survive, he must locate the control center of the legendary engineers who built the planet.

Ever since he joined Omega Force, Captain Jason Burke has lived with the underlying fear that one day Earth would be discovered. His desire to keep Earth's existence and location a secret has driven him to extremes, and kept him far away from his homeworld for a long time. But now Jason's greatest fear is realized, and a fleet of alien ships has attacked his planet. Omega Force rushes to Earth's defense, but the ships are like none they've ever encountered, and employ weapons they have no defense for.

The quadrant is burning. Violent, deadly uprisings are breaking out, seemingly at random, all across the Confederation's sphere of influence. The response by the powerful Confederation Fleet has been swift and decisive, but for every planet they restore order to, another erupts into chaos. Omega Force is working along the frontier worlds when they're forced to come to the aid of a longtime ally and soon realize that the two events are not unrelated.

A scientific experiment begins, and as the button is pressed, the unexpected occurs: everyone in the world goes to sleep for a few moments while everyone's consciousness is catapulted more than twenty years into the future. At the end of those moments, when the world reawakens, all human life is transformed by foreknowledge.

Following an accident that almost cost him his life, Howard Falcon was not so much saved as he was converted, through the use of prosthetics, into something faster, stronger and smarter...but also slightly less human and more machine than he was. And with this change came an opportunity - that of piloting a mission into Jupiter's atmosphere and ultimately of making first contact with the life forms he discovers there.

In the aftermath of the destruction, Shaun finds himself trapped by the winter. With little other choice, he joins a group of survivors doing the best they can. His idea of "best" isn’t always shared by the group, though. But before the weather breaks, when he wants to resume his journey, they all face conflict.

After the sound of the falling bombs fade, as the dark world they live in tries to recover, they have to find a way to adapt to their new reality.

Deep in the steaming jungles of Paraguay, Aimee Weir is in trouble. The petrobiologist has found what she was looking for - a unique microorganism in a natural gas deposit - but it proves to be more destructive than anyone could have imagined. A contagion is striking down all in its wake. The camp is quarantined, but workers start to vanish in the night. Is it fear of contamination - or has something far more lethal come to the surface? Something that has been trapped beneath the miles of stone, waiting... for us.

Sci-fi’s favorite antisocial A.I. is back on a mission.

And Murderbot would rather those questions went away. For good.

The Ministry for the Future is a masterpiece of the imagination, using fictional eyewitness accounts to tell the story of how climate change will affect us all. Its setting is not a desolate, post-apocalyptic world, but a future that is almost upon us - and in which we might just overcome the extraordinary challenges we face.

It has a dark past—one in which a number of humans were killed. A past that caused it to christen itself “Murderbot”. But it has only vague memories of the massacre that spawned that title, and it wants to know more. Teaming up with a Research Transport vessel named ART (you don’t want to know what the “A” stands for), Murderbot heads to the mining facility where it went rogue. What it discovers will forever change the way it thinks.

Jay Gardiner has given himself a fool's errand: to find the remains of his deceased father in the Pacific Ocean off the coast of California. He knows it's a long shot, but Jay feels it's the only way for him to lift the weight of guilt he has carried since his dad's death the previous year. The dive begins well enough, but the sudden appearance of a giant squid puts Jay in very real jeopardy, made worse by the arrival of a sperm whale looking to feed. Suddenly, Jay is caught in the squid's tentacles and drawn into the whale's mouth where he is pulled into the first of its four stomachs.

After 25 years serving as the human Monitor of the Interstellar Ark, Hermes, Orion is scheduled to be placed back into hibernation with the other crewmembers. Knowing he'll die there and be replaced before the ship's voyage is over, he decides that he won’t — can’t — accept that fate. Whatever it takes, Orion will escape Hermes and see what's beyond, even if it means defying the regulations of his only friend — the ship-wide artificial intelligence known as Dan.

In the year 2031, a robot probe detects traces of biological activity on Enceladus, one of Saturn's moons. This sensational discovery shows that there is indeed evidence of extraterrestrial life. Fifteen years later, a hurriedly built spacecraft sets out on the long journey to the ringed planet and its moon. The international crew is not just facing a difficult twenty-seven months: if the spacecraft manages to make it to Enceladus without incident it must use a drillship to penetrate the kilometer-thick sheet of ice that entombs the moon.
