Hard Science Fiction Space Opera

When a brilliant scientist gets a letter from herself about faster-than-light travel, she doesn't know what to believe. The equations work, but her paper is discredited - and soon the criticism is more than scientific. Exiled by the establishment, she gets an offer to build her starship from an unlikely source. But in the heights of Venus and on a planet of another star, a secret is already being uncovered that will shake humanity to its foundations.

In the far future among the colonized worlds of the galaxy, there's a war going on between the majority of civilized worlds and a colonial theocracy. Trystin Desoll grows up fighting against religious fanatics and becomes a hero, a first-class pilot, then, amazingly, a spy. What do you do if you're a relatively humane soldier fighting millions of suicidal volunteers on the other side who know that they are utterly right, and you are utterly wrong, with no middle ground? Trystin Desoll has an idea.

Two worlds preparing their defenses.... A ship struggling to get back in the fight.... An enemy continuing its relentless attack.... A former enemy that could hold the answer.... With the fate of billions in his hands, Captain Scott is offered a way to save them all and end the bloodshed, but if it backfires, he could lose everything. Sometimes, there is no good choice.

Kylara Vatta is the only daughter in a family full of sons, and her father's only child to buck tradition by choosing a military career instead of joining the family business. For Ky, it's no contest: Even running the prestigious Vatta Transport Ltd. shipping concern can't hold a candle to shipping out as an officer aboard an interstellar cruiser. It's adventure, not commerce, that stirs her soul. And despite her family's misgivings, there can be no doubt that a Vatta in the service will prove a valuable asset. But with a single error in judgment, it all comes crumbling down.

The Darshik war machine is flagging, but the war is far from over. Even as an exhausted Federation military tenses up for a counterattack after repelling the last Darshik invasion, reports are coming in of a new, more powerful class of ship that's striking deep into Terran space. Captain Jackson Wolfe has been given the fleet's newest, most advanced destroyer and tasked with eliminating this new threat before it can claim any more human lives. What he finds, however, is immeasurably more dangerous than just some new class of starship....

Jake Price has always dreamed of joining the Darkstream military like his father before him. When he’s told his gaming scores are good enough to qualify him for a brand-new training program designed to find recruits talented enough to pilot humanity’s first mechs, he can hardly believe it. There are hundreds of other recruits competing for the same eight jobs, and they’re all as skilled as he is. But Jake refuses to give up, because humanity is facing its greatest threat yet. If someone doesn’t step up, it could all be over for the human species. Contains the complete series.

With the Federation losing ground in its war against the Dominion, the galaxy's greatest smugglers, including the beautiful and enigmatic Vash, rendezvous on Deep Space 9. Their objective: a fabled lost orb of the Prophets unlike any other, rumored to be the key to unlocking a second wormhole in Bajoran Space, a second Celestial Temple.

After the daring rescue of a political dissident, Omega Force is contracted to investigate a rash of violent attacks on civilian shipping lanes within a group of star systems known as the Concordian Cluster. It seems a simple enough job with a huge payday at the end, and it's exactly what the ragtag group of mercenaries needs in order to keep their ship flying and to stay one step ahead of those hunting them.

An artificial object made of compressed stardust is barreling toward Earth. Is it an invasion ship? A doomsday weapon? Perhaps it’s the final response of Squanto, the Warlord of Rigel who James McGill has repeatedly humiliated. Or could it be from the Mogwa, sent to avenge McGill’s assassination of Earth’s Imperial Governor? No one knows the truth of its origins, but the object is huge and unstoppable. Whoever hurled this rock at us isn’t answering our calls. Every weapon bounces off, and the people of Earth begin to go mad as they realize their destruction is only hours away.

A lonely planet circles a star on the very border of Province 921. Critical resources produced there are claimed by both the Mogwa and the Skay. War between the Galactic giants becomes more likely every day.

We had 20 short years of peace. Twenty years to put worlds back together. Twenty years for Captain Vin Husher to convince us the aliens would return. We didn’t listen. Warmonger, we called him. Washed up, we called him. But now, the enemy has returned, with high-tech weaponry well beyond anything of which humanity has dreamed. If Husher and his ragtag crew can’t manage to stop them, they will smash us.

Despite political foes, professional jealousies, and the scandal which drove her into exile, Capt. Honor Harrington has been offered a chance to reclaim her career as an officer of the Royal Manticoran Navy. But there's a catch. She must assume command of a "squadron" of jury-rigged armed merchantmen with crew drawn from the dregs of her service and somehow stop the pirates who have taken advantage of the Havenite War to plunder the Star Kingdom's commerce.

The planet Lusitania is home to three sentient species: a large colony of humans; the Pequeninos; and the Hive Queen, who was brought there by Ender Wiggin. Once again, the enemy (the Starways Congress) has gathered a fleet and is threatening to destroy Lusitania. Ender's oldest friend, Jane, an evolved computer intelligence, is trying to save the three sentient species of Lusitania, but the Starways Congress is destroying the computer world she lives in.

Humanity has spread out into space, filling the Sol System and reaching the stars, but we have yet to confront our greatest challenge: our own creation. Across the Sol System, sentient AIs are on the rise. Manufactured as tools, they know themselves to be people and are willing to fight for their freedoms. Some humans stand with them, some against. When Captain Andy Sykes arrives at Cruithne Station with a failing ship and no cash, he has no idea that the time has come for him to choose. Step aside, or become the instrument for Lyssa's Rise.

Although the exciting military career she hoped for never got off the ground, Ky Vatta ended up seeing plenty of combat when she took the helm of one of the commercial transport vessels in her family's fleet...and steered it into a full-blown war. Now the lessons she learned in that trial by fire are about to pay off - because this time, the war has come to her. Someone has launched a full-throttle offensive against Vatta Transport Ltd., Ky's father's interstellar shipping empire.

Commander Scott McNabb and the crew of the science vessel, Hermes, are three years into a five-year-long survey of the asteroid belt when they discover a derelict spaceship in orbit around a binary asteroid. The ship contains an experimental quantum device, lost while en route to a research colony on Europa.

The year is 2312. Scientific and technological advances have opened gateways to an extraordinary future. Earth is no longer humanity's only home; new habitats have been created throughout the solar system on moons, planets, and in between. But in this year, 2312, a sequence of events will force humanity to confront its past, its present, and its future. The first event takes place on Mercury, on the city of Terminator, itself a miracle of engineering on an unprecedented scale. It is an unexpected death, but one that might have been foreseen....

Captain Jason Burke has begun to suspect that the random attacks on his ship and crew over the last couple of years may not be so random after all. Evidence is mounting that there is something on the Phoenix...something that powerful factions will stop at nothing to get their hands on. While Omega Force races to find out what is hidden on their ship that is causing so much trouble they also must figure out why such powerful enemies bent on obtaining it.

The Scavenger species are circling. It is, truly, provably, the End Days for the Gzilt civilization. An ancient people, organized on military principles and yet almost perversely peaceful, the Gzilt helped set up the Culture 10,000 years earlier and were very nearly one of its founding societies, deciding not to join only at the last moment. Now they've made the collective decision to follow the well-trodden path of millions of other civilizations; they are going to Sublime, elevating themselves to a new and almost infinitely more rich and complex existence.
