Once a schoolgirl with a street school, Julia is the youngest captive to be exploited in a fatal experiment. The only thing that stands in the way of his freedom is TAU, an artificial intelligence developed secretly by Alex, his enigmatic and masochistic kidnapper. The TAU is equipped with a drone and robot battalion that automates Alex’s ultra-tech house and Alex’s ultra-technological lab, the walls being equiped with screens that project from green fields to images from the depths of space. The TAU’s potential is limited only by its own understanding of the world in which it exists, but it is ready to move to another level.
