The setting: Bolivia in the near future. Miguel "Turing" Saenz, a veteran cryptanalyst, is the most famous code-breaker in the employment of a secret government organization known as the Black Chamber. He is leading the pursuit of the Chamber's latest target: Kandinsky, a "cyberhacktivist" leader who is staging a war against both the government and the country's transnational corporations as part of an antiglobalization revolution. As Turing finds himself drawn into a web of murder, intrigue, and deception, he begins to suspect that his work is not as innocent as he once believed.
