Thomas Cale has been running from his enemies. Believing him to be the incarnation of God's rage, the world's most violent religious sect trained him to destroy His greatest mistake. Mankind itself.

But Cale has other ideas.

Cale is a paradox- arrogant and innocent, generous and pitiless. Feared and revered by those that created him, he has already used his terrifying talent for violence and destruction to bring down the most powerful civilisation in the world.

But having fled to America, Thomas Cale has been caught. He has been given a choice. Murder the American president - the father of that fragile democracy and the the best hope for ending slavery - or be handed over for execution himself.

The survival of rule by the people and the right of millions not to be owned by others rests on Cale's decision.
