Betrayed and left for dead high in the Alps, Nick Stone is in trouble. The blood on his hands tells of a head wound he can't see and his foggy memory confirms it. He knows only one thing for certain - someone, somewhere wants to kill him. And they think they've succeeded.

Stone wants revenge, but the only person who can help him is a seven year old boy. Not much protection in the pursuit of a gang of faceless men who trade in human misery. But this run-of-the-mill close protection task is about to become Stone's most personal mission yet.

Payback is top of Stone's agenda. The fuse has been ignited - but who really holds the detonator?
