Five years after the events of Maelstrom, the corporate elite of North America are hiding from chaos and epidemics on the deep-sea station Atlantis, where they are forced to live side by side with rifters, people adapted to life at great depths. Former enemies united in fear of the outside world, but it has not forgotten about them and is eager to hold everyone accountable. The inhabitants of the station do not yet know that their truce with each other can turn into a full-scale war, that the microbe itself, which destroys all life on the surface of the Earth, has changed and become even more deadly, and on land power now belongs to real monsters, both real and virtual. But in the midst of horror and anarchy, hope appears - a medicine that can heal not only people, but the entire biosphere of the Earth. But won't it turn out to be worse than any disease?
