Their spies were among us for years. They mapped our electrical infrastructure, learned our weaknesses, until finally they flipped the switch and threw us back into the Dark Ages. Only OMBRA and its battalions around the world seem capable of defending Earth from the next wave of attack-terraforming. But at what price can we gain our freedom from these yet-to-be-identified aliens? They're pushing the human race to the edge of extinction if we can't find a way to change things. But what will we have to change? What will we humans become to survive this threat. This is a time for heroes. For killers. And for Grunts. Benjamin Carter Mason will be asked this question over and over as he dives deep into the nasty heart of an alien-transformed Los Angeles. And in the end, he might be the last person on Earth defending not just our lives, but our humanity.
