Hvistendahl makes industrial espionage both understandable and riveting, chiefly by focusing her narrative on two scientists (one Chinese, one American, both manipulated by DBG) who, wittingly and unwittingly, are forced into collecting seeds and information for DBG. This is a complex story, but it’s presented clearly and vividly, thanks to Hvistendahl’s background as a science journalist here and in China; to her exquisite pacing; and to her narrative skills. Unlike many current spy books, which focus on long-ago espionage, this one examines an investigation into the pressing, ongoing problem of industrial espionage. Hard to put down and harder to stop thinking about..
