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.

For 17 years, Colonel Henry Wong and the United Planets Space Force have fought the Kenmiri Empire. They drove the alien overlords back from humanity's borders into their own stars and found allies among the Kenmiri's slaves and subjects. Now the war is over. A great Gathering has been called of the allies who fought the war, but they only ever shared a common enemy. With the Kenmiri in retreat, a thousand new agendas are revealed.

Earth is conquered. Sol is lost. One ship is tasked to free them. One Captain to save them all. When an alien armada destroys the United Earth Space Force and takes control of the human homeworld, newly reinstated Captain Annette Bond must take her experimental hyperspace cruiser Tornado into exile as Terra's only interstellar privateer. She has inferior technology, crude maps, and no concept of her enemy, but the seedy underbelly of galactic society welcomes her so long as she has prizes to sell and money to spend.

The last reward Kira Demirci expected for heroism in a time of war was to spend the rest of her life dodging assassins - but when her government betrays her as part of their surrender, she and her comrades flee the star system of Apollo to the edge of civilized space. The Syntactic Cluster is disorganized, disunified, and in desperate need of the nova fighters Kira smuggled out of Apollo with her. With an entire squadron supposed to follow in her wake, it falls to her to build a new home for her comrades.

An explorer tug captain, Alex Racine detects a damaged alien craft drifting into the system. Recognizing a once-in-a-lifetime opportunity to make first contact, Alex pulls off a daring maneuver to latch on to the derelict. Alex discovers the ship was attacked by an unknown craft, the first of its kind ever encountered. The mysterious silver ship's attack was both instant and deadly.

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.

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.

Aliens exist...and, as it turns out, most of them aren’t that friendly. Jacob Brown wasn’t even born yet the first time they attacked Earth. He was only 14 the second time it happened. When Earth finally came together and fielded its first spaceborne military, Jacob didn’t hesitate to volunteer. Serving aboard a mighty starship, he’d be able to defend his planet - and his family - when, inevitably, they came again.

What would you do if you found a spaceship? Would you call the government, would you pretend you never saw it, or would you keep it a secret? What would you do with it? Use it to gallivant around the galaxy, conquer Earth, get filthy rich, or try to improve life on Earth? Listen along and find out how Marc works to convert Earth into a spacefaring world capable of defending itself and of being united as it meets the other civilizations in the galaxy.

Kira Forrest is a survivor. She's risen above the pain of her beginnings to become a war hero only to leave it all behind in the pursuit of a simple life. Now a salvager, she makes a living sifting through the wreckage of dead alien ships from a war that nearly brought humanity to its knees. After her ship takes damage, she's forced to re-route to a space station where her past and present collide with dangerous consequences. Kira's existence holds the key to a faltering peace treaty with the Tuann - a technologically advanced alien race who dislikes and distrusts all humans.

The human soldiers stranded on the planet Paradise have been recruited into an alien legion to do the dirty jobs that the high-tech species won't do. Their first mission is to kick the enemy off a backwater planet no one cares about. It's a simple assignment, except everyone has a hidden agenda, and the planet could become a deathtrap. 

Isaac Gallant is the heir apparent to the First Admiral. Unwilling to let his mother’s tyranny stand, he joins the rebellion and leads his ships into war against the might of his own nation. Betrayal and failure, however, see Isaac Gallant and his allies captured. Rather than execute her only son, the First Admiral instead decides to exile them, flinging four million dissidents and rebels through a one-shot wormhole to the other end of the galaxy. There, Isaac finds himself forced to keep order and peace as they seek out a new home without becoming the very dictator he fought against.

Quicker is a near-future SciFi/Thriller whose young heroine, Ell Donsaii, is an intrepid athletic phenom who reminds one of David Weber's Honor Harrington. Like Stieg Larsson's Lisbeth Salander in The Girl With the Dragon Tattoo Ell is also a mathematical genius who, instead of counting sheep, works on her own theory of quantum mechanics to help her drift off to sleep. At once shy and concerned about her social skills, yet well loved by those around her, she finds herself at the center of a terrorist plot at the Olympics.

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.
