On the run with his new girlfriend, Malina, they try to figure out what is going on. Not knowing it in the beginning, Sergio finds out Malina’s sister was murdered and blames it directly on Circles. Not knowing who he can trust he works it out with Malina and they continue to find the truth.
The crux of the mystery is that what was found was “socialbots,” bots that parade as people and interact with people and learn using AI algorithms. The bots were going to be used in a bigger plot to sway people to vote for a certain president whose agenda was to bring the US to own over a third of the earth’s rare earth metals. Once in, a Chinese diplomat was going to blackmail him into not doing this as China would lose out a lot of their economy over this.
