Solar Queen serie by Andre Norton

Philip K. Dick Award Finalist
A “ridiculously fun” series debut “with a well-thought-out space opera setting and lots of fancy reveals”—from a Hugo Award winner (Charlie Jane Anders, author of All the Birds in the Sky).
A ragtag space crew discovers alien technology that could change the fate of humanity—or awaken an ancient evil that could destroy all life in the galaxy.
The shady crew of the White Raven run freight and salvage at the fringes of our solar system. They discover the wreck of a centuries-old exploration vessel floating light years away from its intended destination and revive its sole occupant, who wakes with news of First Alien Contact. When the crew informs her that humanity has alien allies already, she reveals that these are very different extra-terrestrials—and the gifts they bestowed on her could kill all humanity, or take it out to the most distant stars.
First serie of the massive polity universe
In outer space you can never feel sure that your adversary is altogether human.
The runcible buffers on Samarkand have been mysteriously sabotaged, killing many thousands and destroying a terraforming project. Agent Cormac must reach it by ship to begin an investigation. But Cormac has incurred the wrath of a vicious psychopath called Pelter, who is prepared to follow him across the galaxy with a terrifying android in tow.
Despite the sub-zero temperature of Samarkand, Cormac discovers signs of life: they are two ‘dracomen’, alien beasts contrived by an extra-galactic entity calling itself ‘Dragon’, which is a huge creature consisting of four conjoined spheres of flesh each a kilometre in diameter. Caught between the byzantine wiles of the Dragon and the lethal fury of Pelter, Cormac needs to skip very nimbly indeed to rescue the Samarkand project and protect his own life.
Gridlinked is the first sci-fi thriller in Neal Asher’s compelling Agent Cormac series.
The Polity, a space-faring civilization ruled mostly by AIs because only they can cope with the math for the runcible operation enabling interstellar travel, has just made first contact.
No one knew quite what to expect of the crablike Prador’s visit to Avalon Station, though the massacre that ensued wasn’t on anybody’s list.
Seems the bloodthirsty Prador are bent on taking over the Polity and its runcible technology.
There is 7 stand alone novel in the polity universe
In the first book of the In Her Name: The Last War trilogy, the Terran survey ship Aurora makes a startling discovery in an uncharted star system: two planets inhabited by an advanced, and decidedly unfriendly, non-human civilization. Disabled by gigantic alien warships before it can escape, the Aurora is boarded by nightmarish blue-skinned warriors with claws and fangs who slaughter the crew in ritual combat using primitive weapons. The sole survivor, Midshipman Ichiro Sato, is returned to Earth as a messenger bearing a device that warns of an impending attack.
If you’re new to the In Her Name series, here is the author’s recommended reading order:
1. The Last War Trilogy
2. The Redemption Trilogy
3. The First Empress Trilogy
The first book in an action-packed new science-fiction adventure series.
Vulcan is a factory planet, centuries old, company run, ugly as sin, and unfeeling as death. Vulcan breeds just two types of native: complacent or tough. Sten is tough.
When his family is killed in a mysterious accident, Sten rebels, harassing the Company from the metal world’s endless maze-like warrens. He could end up just another burnt-out Delinquent. But people like Sten never give up.
From the acclaimed author of Fine Prey, Polymorph, and Evolution’s Darling (Philip K. Dick Award special citation and a New York Times Notable Book) comes a sweeping epic, The Risen Empire, Scott Westerfeld’s dazzling hardcover debut. The undead Emperor has ruled his mighty interstellar empire of eighty human worlds for sixteen hundred years. Because he can grant a form of eternal life, creating an elite known as the Risen, his power has been absolute. He and his sister, the Child Empress, who is eternally a little girl, are worshiped as living gods. No one can touch them.
Not until the Rix, machine-augmented humans who worship very different gods: AI compound minds of planetary extent. The Rix are cool, relentless fanatics, and their only goal is to propagate such AIs throughout the galaxy.
They seek to end, by any means necessary, the Emperor’s prolonged tyranny of one and supplant it with an eternal cybernetic dynasty of their own. They begin by taking the Child Empress hostage. Captain Laurent Zai of the Imperial Frigate Lynx is tasked with her rescue. Separated by light-years, bound by an unlikely love, Zai and pacifist senator Nara Oxham must each in their own way, face the challenge of the Rix, and they each will hold the fate of the empire in their hands. The Risen Empire is the first great space opera of the twenty-first century.
Warlorn is slowly drifting through twilight to neverending night; as the planet sinks into darkness, so its inhabitants face annihilation. Seven years ago, on Avalon, Gwen was Dirk’s lover, his Guenevere; now she wears the jade-and-silver bond of Jaantony Riv Wolf high-Ironjade Vikary, a barbarian visionary, an outcast from his own people for his acts of violence.
And Garse Janacek, Jaan’s shieldmate, is also bound to Gwen – in hatred. Dirk, a rogue and a wanderer, is called to be saviour of the three who are bonded together in love and hate. But in breaking their triangle, he could lose all …
