The ordinary life of Vsevolod Persikov was buried in an instant, along with the one he loved. Despair is a terrible advisor, but it is the only one he has left. For the sake of saving a single person, he stepped into the darkness, selling his soul to the criminal underworld, where the price of freedom and safety is merely a bargaining chip. His carefree days are dead. Now Seva will walk on the edge of a knife, his path illuminated only by the shadows of the past and the cold fire of revenge. He will sweep aside anyone in his path.

But the darkness... it rarely lets go of its own voluntarily. And there is always someone far more terrifying lurking within it. Someone who is already watching.
