"Chthonic Horror" is a fantastic novel by Yan Badevsky, the third book in the “Demonology” cycle; genre: reincarnators, action fantasy, alternate history. The first semester at Adams’ Lyceum has ended. Ilya Nevzorov upgraded to the rank of occultist, got plenty of tasty concessions from the authorities of Neom, and decided to go on a round-the-world trip on an airliner. But a demonologist won’t get to rest quietly. Events are unfolding that could bring Earth to a new apocalypse. The strongest clans are ready to clash with each other, and the spirits of the Abyss are tearing themselves out of anomalies. Only one person will be able to restore order here… Jerg will sow chaos. Woe to anyone who stands in his way.
