Zac Kravitz has upset someone. Someone very important. He has been tortured and cast, barely alive, into an ancient prison deep in the republic of Ta’argistan. Bordering Russia, China and Afghanistan and ringed by high mountains, the country is a land of deep snows and still deeper suspicions, and it’s about to swallow Zac, to drag him from his cell and execute him. But he has a friend. Harry Jones is a former soldier, now a politician, a man of extraordinary skills and an enduring sense of guilt. He owes Zac. The debt must be repaid, no matter what the cost.
