When The Sparrow Falls

In the future, AI are everywhere - over half the human race lives online. But in the Caspian Republic, the last true human beings have made their stand; and now the repressive, one-party state is locked in perpetual cold war with the outside world.

But Paulo Xirau was AI; and as Nikolai and Lily delve deeper into the circumstances surrounding Paulo's death, South must choose between his loyalty to his country and his conscience.
