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.

The assault on Earth was thwarted by the destruction of the aliens' seed ship, but with Mars still under Lanky control, survivors work frantically to rebuild fighting capacity and shore up planetary defenses. Platoon sergeant Andrew Grayson must crash-course train new volunteers - all while dulling his searing memories of battle with alcohol and meds.

The year is 2108, and the North American Commonwealth is bursting at the seams. For welfare rats like Andrew Grayson, there are only two ways out of the crime-ridden and filthy welfare tenements: You can hope to win the lottery and draw a ticket on a colony ship settling off-world...or you can join the service. With the colony lottery a pipe dream, Andrew chooses to enlist in the armed forces for a shot at real food, a retirement bonus, and maybe a ticket off Earth. 

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.

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.

For years, the ancient alien AI known as Skippy (the Magnificent, don’t forget that part) has been able to do one impossible thing after another. What is his secret? It’s simple: 100 percent Grade-A extreme awesomeness. And also because he had never been faced with an opponent of equal power. Until now. This time, he might need a little help from a band of filthy monkeys.

The story of rookie pilot Lt. Halley's first drop ship command. (A short story in the Terms of Enlistment universe.)

There is a personal price to pay for having aligned with the wrong side in a reckless war. For Aden Jansen it's the need to adopt a new identity while keeping his past hidden. Now he's integrated himself aboard the Zephyr, a merchant ship smuggling critical goods through dangerous space. But danger is imminent on planet Gretia, as well. Under occupation, torn between postwar reformers and loyalists, it's a polestar for civil unrest.

In the aftermath of the Battle of Detroit, Corporal Jackson finds out how the 365th AIB got a mauling in the Public Residence Clusters, and why the Territorial Army may have lost control over a big chunk of Detroit. A novella in the Terms of Enlistment universe.

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.

A company of Army Rangers is sent on an interstellar colony ship to secure a foothold on a dangerous, alien planet through violence of action. Leaving behind a warring Earth flung headfirst into a conflict of mutual assured destruction, the Rangers and the accompanying crew of first colonists are guided on a 40-year journey by an unprecedented artificial intelligence. But when they emerge from the frigid embrace of cryosleep, they awake to a nightmare, finding themselves greeted by the same ruthless enemy that brought about the ruin of Earth. 

The problem with lying about having a super weapon is that the bad guys might believe they have nothing to lose by doing something stupid that both sides will regret. Or, they might just call your bluff. Either way, the Merry Band of Pirates need a plan to deal with the Fallout. 

An elite team of SAS special operators battle across the multiverse after a plague of land-hungry sentient robots invade today’s Earth. But, when an aircraft carrier-based counterattack goes horribly wrong, it traps the team in an alien universe with a top-secret group who’ve already saved the world twice. After discovering a dark plot that threatens humanity’s very existence, the two groups jump into action, fighting both on the surface and in orbit in a last-ditch effort to stop the enemy before time runs out.

Their foothold established, Reach and the soldiers sent to secure Amir have only begun to repair the destruction inflicted on them by hostile neighbors when a terrifying new threat emerges from the deep woods and dark jungles of Amir itself. Something so lethal and evasive, not even Brody can seem to take it down. New threats and old enemies arrive as more mysteries of this new home world are uncovered, and with them, clues to humanity’s own mysterious past.

The war should have been over. But it’s not for a group of nationalists grabbing for control. It’s been two weeks since a missile with a nuclear warhead tore through the planetary defenses in the most blistering large-scale attack ever committed in the history of the Gaia system. Commander Dunstan Park of the Rhodian navy has been handpicked to command an experimental cruiser that could dictate the course of the escalating conflict. All he has to do is keep the ship from falling into the wrong hands.
