Dominion

Spec-Ops soldier, First Sergeant Ellis Kirby leads a JSOC unit into the Tora Ghar cave system in Afghanistan in search of WMDs, but finds something much worse. Infected by an ancient power summoned by an evil cleric Kirby and his companions are whisked back to secret military laboratories in the US. The plague of creatures - known as rakes - that is subsequently unleashed threatens to wipe out the entire population of the United States and perhaps the world.
Kirby wakens in his room to discover that everyone in the lab has been slaughtered, and the monstrous flesh-eating creatures are loose and rampaging throughout the land, killing and propagating their species with abandon.
Through a country rapidly overwhelmed by the ravenous creatures, Kirby aims to return home to his parents' farm in Iowa, but on his return – following a perilous cross country journey through rake-infested lands - he discovers that they are dead, so chooses instead to take the fight back to the monsters and their master.
Across the same devastated landscape travel Bree and Jill Adams, sisters at odds, who must face their past to survive the future, and three misfits collectively known as the Ruby gang. Each must endure their travails before all of them are thrown together, and then with Kirby, in a race to the eastern seaboard where the final conflict between man and beast is destined to play out in a battle encompassing modern warfare and ancient magic.
