GRAS Team - Group for the Investigation of Anomalous Situations. This is the name of one of the secret divisions of the FSB, which is engaged in the collection, analysis and investigation of non-standard situations related to unusual properties of the human psyche, unstudied natural phenomena, and events of a military-political nature. The heroes of the GRAS team, born from the imagination of the writer Nikita Velikhanov, attract attention readers due to their originality and obsession. While investigating another case related to the use of viral weapons, GRAS simultaneously contacts a secret organization - the Brotherhood, created to control the power structures of the Russian state.
