While on a carefree vacation in Hong Kong, a former analyst and computer engineer with the National Security Agency has one concern: bargain hunting. Nicole Grant never succumbs to impulse and leads a carefully structured life working in the private sector for an IT security firm. But when a face from the past shows up, the shopping turns deadly. Sold out by her country and targeted for assassination in order to protect an off-the-books covert-action program, Grant's meticulously constructed life is instantly turned upside down. A life-long desk jockey, she's forced to go on the run and team with an untrustworthy, renegade CIA spook. She fights back using what she knows best-computers-to stay one step ahead of her pursuers as she struggles to attain the ultimate form of justice.
