The battle at the galactic center had been a great victory for the Federation and the Alliance but at a tremendous cost. The Battleship Avenger and her fleets had vanished being drawn into a great white vortex at the moment of victory. For over four years, the mystery of what happened to the Avenger has haunted the Federation.

The Lost Fleets have settled on an Originator Dyson Sphere in preparation for their greatest test yet. A great enemy is spreading across the universe conquering galaxy after galaxy. The few surviving Originators have asked Fleet Admiral Jeremy Strong to fight a war against their most hated enemy, the Anti-Life. If he fails to stop their advance, then the entire universe could be in danger.

The Trellixian Empire was constantly expanding, seeking new worlds for its ever-increasing population. If worlds were discovered with existing sentient populations, they were cleansed to make room for colonization. Hundreds of budding civilizations had been eliminated by Trellixian battle fleets. On Earth, years in the past, a scout ship fleeing from the Trellixians crashed. Scientists investigating the wreckage discovered what the Trellixians had done to the world the scout ship escaped from. They also discovered it was only a matter of time before the Trellixians reached Earth.

The Confederation consists of the seven oldest races in known space. They control a vast section of the galaxy. All races in that part of the galaxy are subjects of the Confederation and forced to obey the Confederation’s laws. The Human Empire is well aware of the Confederation and has been careful not to intrude upon Confederation space. However, now the Confederation has decided the Human Empire has grown too large and needs to be brought under control of the seven races.

Thousands of crew are reported dead, including the ship’s captain. Reluctantly, the young XO, Galvin Quintos, will be taking command of the fleet's crippled dreadnaught, the USS Hamilton, while doing his best to bring fleet survivors back to Earth. To make matters worse, there’s a murderer running loose on board the ship, critically low fuel levels, and the Grish are back, in fast pursuit and ready to finish what they’d started. Only by sheer luck - and a good measure of cagey smarts - will Quintos be able to rise to the challenge.

For decades, humans have been exploring farther and farther away from Earth and Newton searching for signs of intelligent life. Now that intelligent life has found them, it comes as an invader.

Geary believed in the Alliance. Even when he uncovered overwhelming evidence that the highest echelons of the government and fleet command were involved in secret programs and prison camps, he believed it was worth saving. He believed his duty was to see that justice was served even though some factions feared that revealing the truth would cause the Alliance to crumble. But after narrowly surviving two assassination attempts when he brings evidence of the misdeeds to the capital star system, Geary realizes that some want to get rid of him.

In the 20th century Earth sent probes, transmissions, and welcoming messages to the stars. Unfortunately, someone noticed. The Galactics arrived with their battle fleet in 2052. Rather than being exterminated under a barrage of hell-burners, Earth joined their vast Empire. Swearing allegiance to our distant alien overlords wasn't the only requirement for survival. We also had to have something of value to trade, something that neighboring planets would pay their hard-earned credits to buy. As most of the local worlds were too civilized to have a proper army, the only valuable service Earth could provide came in the form of soldiers....

The fighting on Tombstone is brutal and deadly, and Jax must find his inner strength if he is to survive.

We were fighting on the wrong side of a war we couldn't win. And that was the good news. 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 come ships of a technologically advanced, aggressive culture, and BAM! There go the good old days, when humans only got killed 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.

When an alien armada destroys the United Earth Space Force and takes control of the human homeworld, newly reinstated Captain Annette Bond must take her experimental hyperspace cruiser Tornado into exile as Terra's only interstellar privateer. She has inferior technology, crude maps, and no concept of her enemy, but the seedy underbelly of galactic society welcomes her so long as she has prizes to sell and money to spend.

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.

The advent of faster-than-light travel has opened up hundreds of habitable planets for colonization, and humans have exploited the virtually limitless space and resources for hundreds of years with impunity. So complacent have they become with the overabundance that armed conflict is a thing of the past, and their machines of war are obsolete and decrepit. What would happen if they were suddenly threatened by a terrifying new enemy?

Seventy years ago, the interstellar supercarrier Ark Royal was the pride of the Royal Navy.

But when a deadly alien threat appears, the modern starships built by humanity are no match for the powerful alien weapons.
