On her maiden voyage, HMS Warspite discovered Vesy, a world populated by primitive aliens, aliens whose culture had already been twisted and warped by human refugees from the First Interstellar War. Now Captain John Naiser and his crew spearhead a diplomat mission to the alien homeworld, hoping to ease them into the galactic mainstream.

HMS Vanguard is the most powerful battleship ever to be commissioned by the Royal Navy, but she is not a happy ship. Her commanding officer is eccentric, rarely seen on the bridge; her former XO has deserted his post; and her first middy is resentful because he hasn't been promoted as he deserves.... But when a first contact mission goes badly wrong, HMS Vanguard and her crew are plunged into an interstellar war against a new and deadly alien threat.

The First Interstellar War is over, but the Royal Navy still has plenty of work to do. As Earth struggles to recover from the bombardment, Captain John Naiser is placed in command of HMS Warspite - an experimental heavy cruiser - and ordered to escort a squadron of colony ships to a star system of immense strategic importance. But as the crew struggle to survive hundreds of light years from Earth, they find themselves dealing with the legacy of the war.

On her last cruise, HMS Vanguard - the most powerful battleship in the Royal Navy - barely survived her encounter with a deadly new enemy. Now, with her commanding officer accused of everything from mutiny to dereliction of duty and her crew under a cloud, the Royal Navy doesn't quite know what to do with her. But there's still a war on. And Vanguard must return to the front lines. Assigned to a task force heading to assist humanity's alien allies, Vanguard and her crew find themselves caught in a deadly alien trap.

Humanity is losing the war. The once-mighty space navies have been crippled, officers and crew have been stretched to the limit and Earth herself has come under heavy attack. The end cannot be long delayed. For Admiral Smith and the crew of HMS Ark Royal, the stakes have never been so high. The one hope is to make contact with alien factions that might oppose the war.

Ark Royal - the Royal Navy’s outdated space carrier - has won a smashing victory against the enigmatic aliens, capturing one of their starships and returning to Earth. Now, Admiral Theodore Smith and his crew are assigned to command a fleet charged with making a deep-penetration raid into alien territory, a fleet made up of carriers from four different nations. But with a crewman who isn't what he seems, untested pilots and international friction - and a new and dangerous alien plan - can Ted and his crew survive their mission?

The first major alien offensive against Earth has been blunted, winning humanity time to deploy new weapons and prepare new tactics as Earth's space navies prepare to take the offensive. But the enigmatic aliens have plans of their own - a full-scale attack on Earth that will either win the war in a single stroke or lose it. The stakes have never been so high. The fate of humanity itself is in the balance.

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 alliance between the Great Powers is starting to fall apart, the human economy cannot keep up with the urgent need for newer and better starships, and politicians are demanding an end to military spending. When a generation starship is detected approaching a British colony world, HMS Invincible is dispatched to intercept the aliens before they can make landfall. But the newcomers bring with them tidings of a new and deadly threat, an expansionist alien race far too close to the Human Sphere for comfort...and a sinister horror beyond human understanding.

The Royal Navy never expected to fight a full-scale interstellar war. Everyone knew the Great Powers would never risk everything on armed conflict when there was plenty of room for everyone in outer space. But when a hostile alien force stumbles across humanity's handful of colony worlds, the Great Powers must set aside their differences and fight to preserve humanity from utter destruction.

The alien virus has begun its offensive, punching through the human defences and sending advance elements to threaten Earth itself. HMS Invincible and her crew, having barely returned from their last mission, are thrown into a desperate mission to strengthen the inner line of defences before the virus can smash them too and destroy the human race. The stakes have never been so high. Defeat means the end of everything.

Earth has fallen. The Core Worlds have collapsed into chaos. War is breaking out everywhere as planetary governments declare independence; entire sectors slip out of contact, and warlords battle for power. The remnants of the once-great Empire are tearing themselves apart. In the shadows, the Terran Marine Corps works to save what little they can to preserve civilization and build a better tomorrow. But powerful factions are competing with them, determined to establish their own order.

The Merry Band of Pirates are in desperate trouble after the end of their last mission, and the real danger to humanity is just getting started. Hostile aliens have discovered there is something odd going on with wormholes in the galaxy, and their investigations could lead to finding a shortcut to Earth....

Earth has fallen. The Empire is no more. Old certainties are collapsing everywhere. Chaos is spreading across the stars, with war following in its wake. Tarsus, a world too close to Earth for comfort, is far from immune. Clarence Esperanza, a reporter on Tarsus, thought he had the story of the century. But, when he took the story to his bosses, he was unceremoniously fired. Cut off from his former friends, abandoned by his wife isolated from the world around him, he thought all he could do was stagger onto the streets and wait to die. 

Space isn't so big after all. The Black Sheep are ready for a vacation. Instead, they get sucked into a black hole that spits them out into an uncharted system with a single rogue planet that's inhabited by an AI force that's none too fond of humanity. From there, they find themselves at the front of a deadly military operation to stop the alien threat before it's too late. The battle against planet rogue has arrived.
