Chthonic in a Coat

In an ordinary Russian city, alongside humans, there live chthonic beings (chthons). They have two forms: human and monstrous, — they can see minor spirits, influence others' emotions, and even eat someone.
Not all people know about the chthons, not everyone believes in them; but there are also those for whom the flickering animal jaws in the crowd do not allow for a peaceful sleep. The main characters of the book are chthons and people aged 20 to 26. Most of them work at the agency "Chthonic in a Coat," where you can order a chthon — as an animator, a friend for an hour, or a nanny for a prickly teenager.
