This takes place a bit in the future where neurolinks are a thing as is a significant AI presence that controls a lot. There are a lot of elements that could be deemed political triggers: Chinese troops referred to as Chicoms, jihadist Iranians that actually set off the apocalypse, Musk, and a calculating president, this one female, but has no feelings of wanting to help any but her inner circle. There is a lot of story with minutiae and unfortunately ends with everyone in that vignette dying-i started just skimming those. The idea of sheltering in a sealed ship at sea is a good one, but could they not have had more ships? The AI is working to the benefit of the few protagonists worth cheering for, but in real life, there would be a major human oversight on the AI decisions and it would not be able to consign "important" government officials to death simply because they were past their childbearing years without a human needing to ok that. That makes some of this less than believable, but I may continue with book 2 to see what happens.
