Deployed in orbit to what he first believed to be a simple research station, a soldier named Markus is a member of a squad defending Earth on the front line of a secret war against an alien enemy that attacks telepathically, using our nightmares as weapons. They don't know what the enemy looks like or even why they are attacking.

What they do know is that Earth is losing.

As they sink further into their deepest terrors, they believe they may finally have the chance to take the fight to their enemy—if the hell they're living in doesn't cause them to tear each other apart first.
