The enemy is coming. The enemy is already here. For years they’ve prepared, plotted, and planned. For years they’ve waited to strike from above and below. Earth is under siege. The enemy covers the landscape. Proxima is unharmed. But that’s about to change. No armies can stop this menace, and no defenses can slow the advance. We are scattered and isolated. We are ignorant and weak. No help is coming. No help remains...or does it? Old heroes will sacrifice everything. New heroes will rise.

Mysterious gateways are appearing throughout the universe, bridging violent civilizations, leading to war, and sowing chaos. While some species succumb to the pandemonium, the Chut’un forge an unholy symbiotic relationship—The Order—with red Europhids, a vast hive intelligence populating the universe’s far reaches. Desiring structure and fearing the unknown, they cull everything opposed to their plan, including the Europhids’ blue counterparts, carrying out a galactic genocide until only one blue Europhid remains...inside Moses Montgomery, a.k.a. "Dark Horse".

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.

In the year 2050, Earth makes first contact. By 2052, the war is over. We lose. Soon after the generation starship Pioneer leaves Earth's orbit, the ship is struck by a rogue asteroid.

Caleb is a former Marine Raider and commander of the Vultures, a search and rescue team that's spent the last two years pulling high-value targets out of alien-ravaged cities and shipping them off-world.

The Deliverance represents a fresh start and a chance to leave the war behind for good. Except the war won't be as easy to escape as he thought.

As a development platform for desperately needed advanced technology, the experimental starship Foresight is the greatest hope humankind has to flee the alien hordes. For test pilot Captain Nicholas Shepherd, the success of the program is even more personal. Successful completion means delivering his wife and son safely off-world and leaving the war behind for good. But when Foresight suffers a critical malfunction during her final scheduled flight, what should have been a minor setback becomes a major fight for survival.

Alliance Navy Commander Grayson Stone is patrolling a nearby space station, when a mysterious starship appears.

While his ship is badly damaged in the assault, Grayson manages to survive. Suddenly trapped behind the front line of the invasion and faced with gut-wrenching choices and near-impossible odds, he'll do whatever it takes to escape the grasp of the terrifying new enemy.

By the divine promise of sacrifice, he awakened an Ash Angel with a new body, new powers, and a new war to fight.

The bad news is, it's the biggest pain in his ass, and she's stranded miles away.

Access points to the ship's controls are sealed, the systems that guide her automated and out of reach.

Until she contacts him, breathless, to tell him she found a body, and it doesn't belong to anyone on board.
