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.
