I let go of her. We each had to fight our own battle now. She looked at me, her eyes the size of saucers as she realised what I had done.

Nick Stone, ex-SAS, now a K' working for British Intelligence on deniable operations, is tough, resourceful, ruthless, highly trained - a master of his trade. Sarah is beautiful, steel willed, intelligent, cunning - the only woman that Stone has ever let under his guard. And now he's been sent to hunt her down ... As the pair are pursued through the backwoods of the American South, Stone's mission becomes a journey to the heart of a dark and deadly conspiracy to which only Sarah holds the key. And as the tension builds to breaking point, the two are led to a confrontation that echoes our worst nightmares.
