It seemed that wars with someone else's mind in the past and the new program set up the awakening Sources for peaceful coexistence with humanity. Then why does the intelligent Top that has arisen around the Taganai Wreck bring death to people and change reality in the most terrible way? Why is Zlatoust destroyed by the Zone flooded with aggressive mutants, and the Changed Terrorists opened a hunt for little Gleb - the son of the Suvaivor Artist? Why doesn't the government allow the use of weapons against the apparently hostile Zone? Two expeditions are sent for answers, but with each of their steps into the depths of the Swamp, questions are only added. And when the Changed comes into play, in whose veins, by chance, the blood of Sid-Spider himself turns out to be, everything becomes completely confusing.
