Dozens died in the attacks, driven mad with fear by a hallucinogenic toxin…and it was all just a smokescreen.

A mysterious network of saboteurs has emerged from the shadows to present the DNI with its greatest threat in recent memory. The discovery of a mole proves to be only the tip of the iceberg as the DNI's investigation reveals a web of influence with puppets in high places – and they want Gabriel to stay out of it.

Rankling at his superiors' orders not to get involved and determined to find out the truth for himself, Gabriel begins digging for answers on his own. But as he works to uncover the network's shadowy agenda, the DNI is also working to keep him in the dark for his own good.

Because the leader of this network is his own father.
