About the book: 2022 / The third book in the "Arcanum" series. The beaches and embankments of New Ingersham are crowded with vacationers, and there are no empty seats in the cafes. Neither locals nor tourists even know what is happening next to them. Meanwhile, ancient legends come to life - a terrible tribe of Gorgonids led by Euryale is preparing to take over New Ingersham, and then the whole world. True, for this they need the help of Lera and Maxim. But what can connect two ordinary teenagers with the monstrous tribesmen of Medusa the Gorgon? And why are the guys being hunted by members of the banned Extropolis corporation? Probably only the insidious cunning and eternal adventurer, the unsinkable Ippolit Bestuzhev, knows about everything..
