A terrorist attack. A killer on the loose. And a final, desperate mission . . .

Former SAS Captain, Tom Jackson, is a man with nothing to lose. A veteran of the most dangerous missions the Regiment could throw at him, his life was torn apart the day a terrorist attack killed his family. Now he grieves in obscurity, the world of warfare nothing but a distant memory.

However, people higher up the chain of command have other plans for Jackson. They are in a mess of their own making, and make him an offer he can't refuse - an offer that will take him back into the brutal theatre of war. There's a disaster waiting to happen, which only one person can help prevent, and that person is being held by the Taliban insurgency in the depths of a harsh Afghanistan winter.

As Tom reluctantly prepares for this final mission, he does so in the knowledge that it will stop a devastating terrorist attack - as well as satisfy an ulterior motive of his own. But as events begin to unfold, Tom suspects that someone is playing a game with him; that nobody can be trusted; and that in the murky world of international terrorism, things are seldom what they seem . . .
