In Thailand, Anderson Lake is a calorie company man working for big business. Under cover as a factory manager, he combs Bangkok's street markets in search of near-extinct foodstuffs. And there he meets the Windup Girl, the beautiful and enigmatic Emiko — now abandoned to the streets. She is one of the underclass of New People, creche-grown and bred to suit the whims of the rich. Engineered as slaves, soldiers and toys, they are seen as soulless by some and as devils by others. As Lake becomes more drawn to Emiko, conspiracies breed within his working life becomes and the politics of a troubled age threaten to spiral out of control. The pressures mount as what he should do conflicts with what he wants to do, threatening to bring down his world. So what happens when bio-terrorism becomes a tool for corporate profits? And could bio-terrorism's genetic drift force mankind to the cusp of post-human evolution?
