When war comes, the Earth is not ready. An immortals war arrives, the only warning a flash of light and energy 660 million kilometers away. A curiosity, passed off to NASA and tucked away in a note to be ignored. Only the flash of light is not the end, it is the beginning. Admiral Zachary Quinn is about to have a very bad day, and he is not alone. The war is here. Our response must be fast, it must be sure, and it must be victorious. Who wants to live forever?

When the Colony on Hayden's world went black, a team was sent to investigate. It was supposed to be a training mission: skip in, find out the Casimir Transmitter had gone dead, report back and wait for resupply from the Fleet. By the time the only surviving member of the team made landfall, it was spectacularly clear that this wasn't a training mission.

Former Marine Captain Alexander Hale only wanted a weekend out with some old buddies. He could have done without the gang war, the shootout, and...oh yeah, the alien abduction. Now he's in the middle of something he doesn't understand, never asked for, and is having quite possibly the greatest time of his life. Semper Fi and which way are the shores of Tripoli anyway?

The world fell, the invaders won, and demons now ruled what had once been man's domain. The great works of a once powerful civilization lie in ruins, its people having forgotten the wonders of their forefathers as they now live in the yoke. Not everyone is willing to go quietly into the endless night, however. Human pests still infest occasional parts of the conquered world. In one nearly uninhabitable part of that world, a very young such pest has come of age and, without understanding what it means, she walks in the shadow of destiny.

Humanity has reached an uneasy truce with the Empire - but unless the allies bring the fight to the enemy, extinction is all but assured. In preparation for the inevitable next war, Commander Stephen Michaels is at the helm of the Archangel Squadron, and his orders are simple: go rogue. Disguised as mercenaries, Commander Michaels and the Archangels seek valuable intelligence on their imposing foe. Their mission takes them deep into uncharted territory, where they make inroads with the Empire, fiercely guarding their true identities and purpose.
