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....

Aliens exist...and, as it turns out, most of them aren’t that friendly. Jacob Brown wasn’t even born yet the first time they attacked Earth. He was only 14 the second time it happened. When Earth finally came together and fielded its first spaceborne military, Jacob didn’t hesitate to volunteer. Serving aboard a mighty starship, he’d be able to defend his planet - and his family - when, inevitably, they came again.

Convicted of a minor traffic violation, Rev Pelletier is conscripted into the Perseus Union Marine Corps...for up to a 30-year term of service.

But with extremely high mortality rates, can he and his friends survive until their term of service is over?

Worse, she claims to have permission from the Wardens to unleash them upon the system.

Mars and the Moon have been colonized, piracy runs rampant in the asteroid belts, and a thriving society grows in the depths of space. Humanity prepares to embark upon its greatest journey - the colonization of Alpha Centauri. Then, everything changes. A deep space reconnaissance probe discovers a new Earth-like planet 12 light-years from Earth’s sun. The probe also finds something unusual, something unnerving. A new mission is created, a space fleet is formed, and humanity embarks on unravelling the greatest mystery of all - the origins of life itself.

From scratch.

The aliens tested humans on an individual basis for miner rentals. Do well on your pilot test, get a spaceship, sign up with a corp, and you can mine the belt. For a puddle-jumper pilot like me, yeah, I was so interested I became obsessed. When I finally tested, I performed above and beyond, being offered a contract for some better than a miner - Earth's First Starfighter.

Two hundred years ago, aliens invaded Earth. A violent war followed. The enemy won. Some of us escaped, most of us didn’t. On Proxima they flourished - the invasion forgotten. On Earth we floundered - the horror began. Their world is advanced, peaceful, and secure. Our world is broken, savage, and overrun. A new invasion is coming. A hunger that has swallowed half the universe. They don’t care which planet we live on. They want to end us all. But where there is life, there is hope. And where there is hope, there are heroes. This time, vengeance will be ours.

With enemies at home and in the darkness beyond, a team of unlikely heroes-a janitor, a mercenary, an asteroid miner, and a pirate-are the only ones who can avert a second apocalypse. This set includes the first three books of the newly-finished REBEL STARS series.

Once, Jackson Rook was a war hero. Raised from boyhood to pilot an exosuit mech, he’d fought gallantly for the rebellion against the Collectivists. But that was a long time ago, on a world very far away. Now, Jackson Rook is a criminal, a smuggler on board the Multipurpose Supply Vehicle Tar Heel. His latest mission: steal a top-of-the-line mech called the Citadel and deliver it to the far-flung planet Swindle, a world so hostile even the air will kill you. The client: a man known only as the Warlord.

In the beginning, the gods destroyed the world. Five hundred years later, things haven’t gotten much better for humans. The demigods that were left behind to guard over humanity have been using them as fodder for an endless civil war between themselves, and the humans just go on dutifully slaughtering each other, battle after battle. It’s not all bad, though. Perry McGown makes his living off those bloody, stinking battlefields. He works on a crew that reclaims all the spent shell casings. But if anyone found out that he was a deserter from the war, he’d be executed for heresy.
