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 But now, her weapons are outdated and her solid-state armour nothing more than a burden on her colossal hull.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.

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.

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?

As a crumbling Galactic Republic falls to the relentless assault of a merciless foe, so begins the rise of an enigmatic emperor intent on saving a corrupt galaxy-spanning civilization from itself…and from something much darker that lies beyond the reaches of the known. Just as the reins of power fall into his iron-fisted grasp, an assassination attempt by a hidden cabal within his own inner circle jeopardizes every plan he has set in motion for his Dark Legion, his Imperial Navy, and his ultimate conquest of the stars. But the assassins have no idea who they're actually dealing with.

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.

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.

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.

From the Audie-nominated narrator of The Martian. In eleven years' time, a million members of an alien race will arrive at Earth. Years before they enter orbit, their approach will be announced by the flare of a thousand flames in the sky, their ships' huge engines burning hard to slow them from the vast speeds needed to cross interstellar space. These foreboding lights will shine in our night sky like new stars, getting ever brighter until they outshine even the sun, casting ominous shadows and banishing the night until they suddenly blink out.

The Phage War had been a devastating conflict for the Terran Confederacy. Even with the destruction of their terrifying, implacable foe, humanity is still reeling. Political alliances are crumbling, and their mighty fleet is in tatters. There is nothing to celebrate, even after such a complete victory. They soon learn that there are other stellar neighbors - and they've been watching the conflict with great interest. One species comes with an offer of friendship and alliance, but humanity is weary and distrustful.

They hunt us. They bomb our worlds for target practice. A star cluster in the constellation of Orion rotates once every 1,000 years. Those who rule there have an ancient tradition: When each cycle ends, they train their fleets by spilling the blood of lesser beings. The enemy fleets are coming again. In response, the Rebel Worlds gather their starships to face the terrifying threat, and this time humanity is asked to stand with them. The last time they considered Earth, Vikings in longboats were raiding English coastlines. Today, we're less primitive. Today, we're a target.
