A race of feline aliens have discovered a new source of prey. Unfortunately, humanity is distracted as a sentient bio-computer is orchestrating an interstellar civil war. Neither side is yet aware that they have been detected by a star-faring race of predators, who are already making preparations to unleash humanity's greatest nightmare: alien invaders.

Ian Stevens, director of the Deep Space Research Institute, isn’t interested in conducting research just for the sake of research. While the rest of the world - including the US Government - thinks that’s the DSRI’s sole mission, Stevens is actually interested in more - he wants manned space travel and the colonization of the moon. With NASA defunct, few scientific probes are being launched, and no one even talks about human spaceflight anymore. Stevens is out to change that.

One starship will either save Earth or destroy her. A century ago our star erupted, destroying Earth's wormhole network and closing off trade with her colonized planets. After being out of contact with the younger worlds for so many years, humanity is shocked when a huge ship appears at the edge of the solar system. Our outdated navy investigates, both curious and fearful. What they learn from the massive vessel shocks the planet.

Seventy years ago, the interstellar supercarrier Ark Royal was the pride of the Royal Navy. But now, her weapons are outdated and her solid-state armour nothing more than a burden on her colossal hull. She floats in permanent orbit near Earth, a dumping ground for the officers and crew the Royal Navy wishes to keep out of the public eye. But when a deadly alien threat appears, the modern starships built by humanity are no match for the powerful alien weapons.

Earth is no longer the center of the universe. After the invention of the faster-than-light jump drive, humanity is rapidly establishing new colonies. But the vast distances of space mean that the old order of protection and interstellar law offered by Earth has ceased to exist. When a nearby world attacks, the new colony of Glenlyon turns to Robert Geary, a young former junior fleet officer, and Mele Darcy, a onetime enlisted marine.

The Hundred Worlds have withstood invasion by the relentless Hok for decades. The human worlds are strong, but the Hok have the resources of a thousand planets behind them, and their fleets attack in endless waves. The long war has transformed the Hundred Worlds into heavily fortified star systems. Their economies are geared for military output, and they raise specialized soldiers to save our species. Assault Captain Derek Straker is one such man among many.

The authority of the Syndicate Worlds’ government is crumbling. Civil war and rebellion are breaking out in many star systems, despite the Syndic government’s brutal attempts to suppress disorder. Midway is one of those star systems, and leaders there must decide whether to remain loyal to the old order or fight for something new.

Out of the blue, a young Space Fleet officer's dream becomes reality: He's made captain of a starship. Just in time for the return of humanity's most terrible enemy, after 50 years of peace. To survive against this enemy, Captain Tad Thatcher will have to do more than learn how to become an effective commander, or how to wrangle his wayward crew. He will need to reinvent space combat. From scratch.

The Confederation has fought three wars against the forces of the totalitarian Union. Three generations of its warriors have gone off to war, held the line against the larger, more powerful enemy. Now the fourth conflict is imminent, and the Confederation's navy is on alert, positioned behind the frontier, waiting for the attack it knows is coming.

Spacers call the warp point Charon's Ferry. No star ship has ever entered it and returned since a vengeful Orion task force pursued a doomed Terran colonization fleet into it in 2206. Almost a century has passed. The fiery hatreds of a quarter-century of warfare between the Terran Federation and the Zheeerlikou'valkhannaieeee, the cat-like species humans called the "Orions", have eased at least a little.

When a bunch of interstellar scavengers approach Earth intending to abduct a few dozen humans and sell them into slavery in the darkest, they make the mistake of picking on Steve Stuart and his friends, ex-military veterans all. Unprepared for humans who can actually fight, unaware of the true capabilities of their stolen starships, the scavengers rapidly lose control of the ship - and their lives.

The Star Kingdom has a new generation of officers! And this elite group hand-picked and trained by Honor Harrington herself is going to be needed immediately, as their first assignment turns out to be more dangerous than anyone expected. What was supposed to be a quiet outpost, far from the blazing conflict between the Star Kingdom of Manticore and the People's Republic of Haven has actually been targeted by an unholy alliance between the slaveholders of Manpower.

In the year 2420, war looms between the galaxy's two most powerful empires: the tyrannical Theocracy and the protectionist Commonwealth. Caught in the middle sits the occupied outpost system Cadiz, where young officer and aristocrat Katherine "Kat" Falcone finds herself prematurely promoted at the behest of her powerful father. Against her own wishes, Kat is sent to command the Commonwealth navy's newest warship, Lightning.

Damien Montgomery is as much a nobody as a Mage of the star-spanning Protectorate of Mars can be. Trained as a Jump Mage, one of the elite who teleport ships across interstellar space, he lacks the connections to find a ship that will take him. Until pirates and politics strand Captain David White of the jump freighter Blue Jayin his home system. The two men's matching needs birth a choice and a partnership that will take them from high-end orbitals to prisons to alien graveyards in forgotten star systems.

Returning home after a training exercise, Captain Jonathan Somerville and his ship, HMS Achilles, stumble into the middle of the warzone. Stranded behind enemy lines, the crew of Achilles must fight their way through occupied territory if they are to link up with coalition forces and help turn back the invaders.
