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.
