There’s only one place he can go for answers: the Institute for Post-Human Research. But nothing at the Institute is the same. His room is more like a cell, and outside the window, huge searchlights sweep the skies and robot vehicles roam the grounds. William’s old teachers won’t tell him what’s going on although it’s obvious that everyone is frightened of something—or someone. When his friend Iscia finally arrives, William thinks he may have found an ally, but she’s hiding things as well.
