Did some of them still remain in the Solar System, or is this a new generation of strange, half-alive, inhuman beings? What are they planning? What will this mean for people? Those questions will have to be answered by Artem Romashin, an officer of the Security Service and the chief “Specialist on Demons.” As has happened more than once, Artem’s investigation leads to utterly unexpected results that are of enormous importance for humankind.
