WHAT LIES AHEAD IS ALREADY HERE...

America is a difficult place to live below the surface. But Gabriel and Michael Corrigan are trying to do just that. Since childhood, the brothers have been shaped by the stories that their father has told them about the world in which they live. Since his mysterious disappearance, they have been living 'off the grid' - that is, invisible to the intrusive surveillance networks that monitor our modern lives.

But no-one is as invisible as they would like to believe. Nathan Boone, a mercenary, has been tasked to hunt down the brothers. The only person who stands between them and certain death is Maya, a tough young woman playing at leading a normal life. But her background is anything but normal. She has been trained to fight and survive at whatever cost.

When she is summoned to protect the brothers, she must leave everything behind if she is to succeed.
