Since the Dark Ages, when werewolves, mermaids, goblin, brownies lived with people, each of us carries fragments of the genomes of relict races in our blood. Most deal with the dark part of their soul relatively easily, driving the ghosts of the past to the very bottom of the subconscious; someone needs the help of the Church or a psychoanalyst, someone muffles the voice of someone else's blood with vodka and drugs... But there are those who voluntarily let in the Night, and the Darkness of their souls burst out, taking them beyond the brink of death, forcing them to pay for the "unbearable lightness of being" with other people's lives. If these Children of the Night, hungry for destruction and blood, gain power, they will turn Russia into hell on earth. Who will save our world from the undead and evil spirits? Who will overcome the carriers of Darkness? Who will triumph in the secret BLOOD WARS that have been going on for more than a millennium?...
