Dr. Timothy Ryan, head of the military psychiatric unit at Grantham Barracks, is meeting a new patient, a woman known as Prisoner Alpha. As she is being transferred, they are attacked by assassins, barely escaping with their lives. One shooter vanishes, leaving behind a dead companion unlike anyone Ryan has ever seen. But even more baffling is the puzzle of Alpha herself. She speaks in a strange tongue, and doodles in bars, dots, and little pictures like nothing Ryan has ever seen. Is she some sort of savant, or the most cunning spy he's ever met?

Until a cyber-attack collapses the American banking system, and an already fractured nation descends into anarchy and chaos.

The aged healer Tocho has to stop him, but to do it he must ally himself with the bitter and broken witch hunter, Maicoh, whose only goal is achieving one last great kill.

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....

Few know the warship’s actual name. But everyone has heard the rumors. The PUV James Keeling can do something no other vessel in existence can do—slip into another dimension, travel undetected, then re-emerge onto our plane and surprise enemy targets. But the thing that makes the Crypt unique also makes it a nightmare for those onboard; interdimensional travel causes hallucinations, violent behavior, and psychotic breakdowns. Keeling could be the Union’s greatest weapon, a game-changing asset that can defeat the bloodthirsty zealots of the Purist Nation, the Union’s mortal enemy.

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.

They are coming. The countdown has begun. First visible only as blips on a telescope image, the discovery of objects approaching from Jupiter's orbit immediately sets humanity on edge. NASA doesn't even bother to deny the alien ships' existence. The popular Astral space app (broadcasting from the far side of the moon and accessible by anyone with Internet) has already shown the populace what is coming.

Darrow—and Reds like him—are nothing more than slaves to a decadent ruling class.

No one has ever ventured deeper into space than the four astronauts of Shepherd-1. The aim of their mission is to witness the creation of the cosmos. Using the sun as a lens, they are to align a flock of probes in such a way that the moment of the Big Bang becomes visible. For astronomer Christine, this is a dream come true. So she is bitterly disappointed when the first images are obscured by a kind of veil that prevents any insight. She works obsessively to find a solution, but when she finally succeeds in lifting the veil, she sees something that would have been better kept hidden...

For dinosaurs, it was a big rock. For humans: Coronal Mass Ejection (CME). When the Earth is hit by the greatest CME in recorded history (several times larger than the Carrington Event of 1859), the combined societies of the planet's most developed nations struggle to adapt to a life thrust back into the Dark Ages. In the United States, the military scrambles to speed the nation's recovery on multiple fronts including putting down riots, establishing relief camps, delivering medical aid, and bringing communication and travel back on line. Just as a real foothold is established in retaking the skies (utilizing existing commercial aircraft supplemented by military resources and ground control systems), a mysterious virus takes hold of the population, spreading globally over the very flight routes that the survivors fought so hard to rebuild.
