The Ruhar hit us on Columbus Day. There we were, innocently drifting along the cosmos on our little blue marble, like the Native Americans in 1492. Over the horizon came ships of a technologically advanced, aggressive culture, and BAM! There went the good old days, when humans got killed only by each other. So, Columbus Day. It fits. When the morning sky twinkled again, this time with Kristang starships jumping in to hammer the Ruhar, we thought we were saved.

John Perry did two things on his 75th birthday. First, he visited his wife's grave. Then he joined the army. The good news is that humanity finally made it into interstellar space. The bad news is that planets fit to live on are scarce - and alien races willing to fight us for them are common. So, we fight, to defend Earth and to stake our own claim to planetary real estate. Far from Earth, the war has been going on for decades: brutal, bloody, unyielding.

When Ivan Pritchard signs on as a newbie aboard the Mad Astra, it's his final, desperate stab at giving his wife and children the life they deserve. He can survive the hazing of his crewmates, and how many times, really, can near-zero g make you vomit? But there's another challenge looming out there, in the farthest reaches of human exploration, that will test every man, woman and AI on the ship - and will force Ivan to confront the very essence of what makes him human.

AD 2204. An alien shipwreck is discovered on a planet at the very limits of human expansion - so Security Director Feriton Kayne selects a team to investigate. The ship’s sinister cargo not only raises bewildering questions but could also foreshadow humanity’s extinction. It will be up to the team to bring back answers, and the consequences of this voyage will change everything. Back on Earth, we can now make deserts bloom and extend lifespans indefinitely, so humanity seems invulnerable. We therefore welcomed the Olyix to Earth when they contacted us. But were the Olyix a blessing or a curse?

All Systems Red is the tense first science fiction adventure novella in Martha Wells' series The Murderbot Diaries. For fans of Westworld, Ex Machina, Ann Leckie's Imperial Raadch series, or Iain M. Banks' Culture novels. The main character is a deadly security droid that has bucked its restrictive programming and is balanced between contemplative self-discovery and an idle instinct to kill all humans.

Our universe is ruled by physics, and faster-than-light travel is not possible - until the discovery of The Flow, an extradimensional field we can access at certain points in space-time that transports us to other worlds, around other stars. Humanity flows away from Earth, into space, and in time forgets our home world and creates a new empire, the Interdependency, whose ethos requires that no one human outpost can survive without the others. It's a hedge against interstellar war - and a system of control for the rulers of the empire.

Humanity has colonized the planets - interstellar travel is still beyond our reach, but the solar system has become a dense network of colonies. But there are tensions - the mineral-rich outer planets resent their dependence on Earth and Mars and the political and military clout they wield over the Belt and beyond. Now, when Captain Jim Holden's ice miner stumbles across a derelict, abandoned ship, he uncovers a secret that threatens to throw the entire system into war.

When Rosemary Harper joins the crew of the Wayfarer, she isn't expecting much. The ship, which has seen better days, offers her everything she could possibly want: a small, quiet spot to call home for a while, adventure in far-off corners of the galaxy and distance from her troubled past. But Rosemary gets more than she bargained for with the Wayfarer. The crew is a mishmash of species and personalities, from Sissix, the friendly reptilian pilot, to Kizzy and Jenks, the constantly sparring engineers who keep the ship running. Life on board is chaotic, but more or less peaceful - exactly what Rosemary wants.
