Space Military Science Fiction

United Nations Special Operations Command sent an elite expeditionary force of soldiers and pilots out on a simple recon mission, and somehow along the way they sparked an alien civil war. Now the not-at-all-merry band of pirates is in desperate trouble, again. Their stolen alien starship is falling apart, thousands of light years from home. The ancient alien AI they nicknamed Skippy is apparently dead, and even if they can by some miracle revive him, he might never be the same.

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.

Rapid colonization of the moon is pushing both national space agencies and powerful corporations to negotiate a New Lunar Accord in an effort to prevent escalating conflicts over valuable resources and territory.

Now it’s only a matter of weeks before the ever-increasing debris cloud makes travel back to the home planet impossible.

The Merry Band of Pirates offered the bad guys a ceasefire. We won’t mess with them, if they don’t mess with us. Easy, right? No. The aliens chose to do things the hard way. So, the Pirates are racing around the galaxy to clean up the threat to Earth. The infant UN Navy has their own mission with the Alien Legion: Get humanity some allies in the fight. And the Ethics & Compliance Office might have to do something...ethical. Unless they can find a way around it.

Not for the Merry Band of Pirates.

Kylie Rhoads is a junker. She makes her living traveling the stars, salvaging abandoned ships left over from pirate attacks on the edge of the Gedri system.

The SA Space Force, just the people Kylie wants to avoid. To avoid prison, Kylie makes a deal to go deep into the Gedri System and rescue a simple girl.

A mysterious wave of light has swept across the globe, erasing all animal life from the planet in an instant. Now, two survivors are all that remain—one stranded on a ravaged Earth and the other newly rescued from the decaying International Space Station. Their struggle for survival and reunion soon spirals into something much larger, plunging them into a cosmic battle that transcends time, space, and even reality itself.

The Merry Band of Pirates stopped the enemy from stealing a Sentinel, and destroyed its Elder starship, so why weren’t the Pirates planning a victory party? The enemy was not what they thought it was. It was much, much worse.

The Aftermath of a stunning victory—especially an unexpected, complete, and final victory—should be high-fives all around, listening to politicians give boring congratulatory speeches, and a well-deserved rest for the Merry Band of Pirates. Yes, the galaxy is still a freakin' mess, but that is nothing new, and for a change, that can be someone else's problem. Until, you know, something really bad happens, and only the Pirates can deal with the problem... Or not.

Far from Earth, the war has been going on for decades: brutal, bloody, unyielding. Earth itself is a backwater.
