In the fourth book of the Extinction Wars series, Abaddon commands a Karg-Jelk Super Fleet bent on annihilating humanity. He's the galaxy's most ruthless strategist wielding superior technology. That includes the perfect raid-ships, able to teleport anywhere at will. Humanity has Commander Creed, and he has his Assault Troopers. He's going to take the fight to the enemy. He's buying time, learning secrets and setting up for the greatest space battle in the Orion Arm.

Imagine a ship the size of a planet. It has an atmosphere of methane, but there is no water. Mysterious and dark, it sails through a gateway, leaving a path open to the most implacable enemies that mankind and the aliens of the Milky Way Galaxy have ever face. Genetically tailored, symbiotic body armor protects the human commandos that are to be dropped on the metallic surface. A trooper in his armor, with surgically enhanced, neuro-fiber speed, is the deadliest grunt in the universe.

The Earth died when aliens rained thermonuclear warheads on her cities and sprayed the surface with a bio-terminator. A deadly poison drifted to every corner of the planet, threatening the last survivors with annihilation. For a soldier like Creed, there is only one way to keep breathing untainted air. He must bury his hatred of the extraterrestrials and join the Jelk Corporation as an assault trooper, leaving the planet for outer space. In return for his and other people's services, the corporation will house the last humans for as long as the assault troopers keep winning.

Billions died before humanity clawed its way up from the brink of extinction, defeating the aliens that treated us like mere beasts. After years of agonizing toil and hardship, we have finally built a first-rate fleet, forcing our hostile neighbors to accept our freedom. But in the center of the galaxy, a bitterly vengeful woman discovers the secret of the Plutonians. She is going to awaken them so the extraterrestrials can attack us with the deadliest ships in existence. If the Plutonians destroy our fleet, the others will surely swarm in like locusts and kill us.

Across the six-planet expanse of the Gaia System, the Earthlike Gretia struggles to stabilize in the wake of an interplanetary war. Amid an uneasy alliance to maintain economies, resources, and populations, Aden Robertson reemerges. After devoting fifteen years of his life to the reviled losing side, with the blood of half a million casualties on his hands, Aden is looking for a way to move on. He’s not the only one. A naval officer has borne witness to inconceivable attacks on a salvaged fleet. A sergeant with the occupation forces is treading increasingly hostile ground.

Earth's armed forces have stopped the Lanky advance and chased their ships out of the solar system, but for CDC officer Andrew Grayson, the war feels anything but won. On Mars, the grinding duty of flushing out the twenty-meter-tall alien invaders from their burrows underground is wearing down troops and equipment at an alarming rate. And for the remaining extrasolar colonies, the threat of a Lanky attack is ever present.

The Terran Union must launch one last desperate assault to save itself, but the enemy is legion and ready to crush the battle-weary human forces. Earth needs the Ibarra Nation to join the fight, but Stacey Ibarra has other plans. She hunts for a super weapon that will forever alter the balance of power in the galaxy, all the while her mind teeters on the brink of insanity. Roland, her loyal Armor soldier, must decide if she can be trusted to wield the Ark, or if she’s too dangerous to rule the nation he swore to defend.

Mars has been under Lanky control for more than a year. Since then, the depleted forces of Earth's alliances have rebuilt their fleets, staffing old warships with freshly trained troops. Torn between the need to beat the Lankies to the punch and taking enough time to put together an effective fighting force, command has decided to strike now.

War rages across the galaxy. And humanity is losing battle after battle. The renegade Armor, Roland, seeks the key to victory against the enemy encroaching from all sides. An Aeon guards a secret which will tip the balance of power in the galaxy. But first, Roland and the Ibarra Nation must defeat her guardians, the Cyrgal. On another front and amid the tumultuous aftermath of Roland’s defection, Gideon leads a desperate attempt to assassinate a Kesaht general. He is the last hope to turn the tide of the battle and save the world of Ouranos.

The human soldiers stranded on the planet Paradise have been recruited into an alien legion to do the dirty jobs that the high-tech species won't do. Their first mission is to kick the enemy off a backwater planet no one cares about. It's a simple assignment, except everyone has a hidden agenda, and the planet could become a deathtrap. 

When Roland and his lance rescue an Ibarra crew from a Kesaht attack, those saved become a pawn in a conspiracy that could turn the galaxy against all of humanity. Earth’s senior leaders must sacrifice the captured crew to preserve the peace, or risk war with the Ibarra Nation. But Stacey Ibarra and her lieutenants have plans of their own. Roland, torn between his duty as a Templar and his loyalty to his home world, is thrust into the struggle between the Ibarras and Earth. He must choose between the factions, and there will be no turning back.

The remnants of the Expeditionary Force stranded on the alien-controlled planet "Paradise" get a chance to prove themselves, in a simple off-world training mission with a ship full of teenage alien cadets. When the mission goes horribly wrong and the survival of everyone on Paradise is at risk, the Merry Band of Pirates may have to come to the rescue. Unless they get killed first.... 

The Interdependency, humanity’s interstellar empire, is on the verge of collapse. The Flow, the extra-dimensional conduit that makes travel between the stars possible, is disappearing, leaving entire star systems stranded. When it goes, human civilization may go with it - unless desperate measures can be taken. Emperox Grayland II, the leader of the Interdependency, is ready to take those measures to help ensure the survival of billions. But nothing is ever that easy.

The alien forces known as the Lankies are gathering on the solar system's edge, consolidating their conquest of Mars and setting their sights on Earth. The far-off colony of New Svalbard, cut off from the rest of the galaxy by the Lanky blockade, teeters on the verge of starvation and collapse. The forces of the two Earth alliances have won minor skirmishes but are in danger of losing the war.

Vicious interstellar conflict with an indestructible alien species. Bloody civil war over the last habitable zones of the cosmos. Political unrest, militaristic police forces, dire threats to the solar system.
