Set in the Warhammer 40k universe, but accessible to those unfamiliar with the setting.

The Imperium of Man has been fighting the Long War for ten thousand years. It is a war fought simultaneously across thousands of stars and against innumerable enemies. On smoke-filled battlefields and in the cold emptiness of the void the military might of the Imperium stands strong in the face of horrifying foes. It is not a war fought to conquer new lands, or to seize the wealth of enemy nations. It is a war fought to hold what they have, or to regain what they have already lost.

The world of Nova Iberia is far from that war and supports the Imperium by sending her finest sons to foreign stars to fight and die as elite commandos in the Imperial Guard. A chance discovery on the corpse of one of these commandos has cast doubts around the world's loyalty, and has drawn the attention of the Imperial Inquisition. The seekers of the Alien, the Heretic and the Daemon have descended upon this peaceful world, and they will not leave it intact.

Primaris Psyker Amelia Lafayette was a ward of the state, now bound as an acolyte to the Inquisition in recognition of her telepathic gifts. Inexperienced, and browbeaten by her training, she must adapt to her new circumstances or fall. If she can navigate the tangled webs of heresy, and survive life in the Inquisition, then she may find the opportunity to prove herself worthy of greater authority.
