Penny Lee, an industrial spy and professional honey trap, has lost her career and all she possesses. She holes up in a remote Japanese training camp to lick her wounds and avoid a long list of enemies - a shelter made all the more appealing by the arrival of David Diya, an antiques dealer she falls for, despite her best instincts. Shimura, her aikido master, has other plans for her. Revealing his awareness of her past life, Shimura coerces Penny into becoming his assassin: first target, a South Korean tycoon. The plot goes wildly wrong, leaving Penny at the mercies of an American spy with an interest in artificial intelligence, a Korean scientist gone rogue, and Chinese military officials who know more about Penny's past than she does - and are willing to share what they know...for a price.
