Amid the impenetrable thickets and cloying quagmires—where no person has ever gone—a war between the unclean has been raging for a long time. Once, the forest lands were ruled by the wise and just Zhiv, but he fell at the hands of the cruel ruler of the swamps—Mora, his half-brother.
Since then, the swamps have been spreading year by year into a black morass, squeezing the forest and threatening to bring it to ruin. Where once vigilant forest-spirits stood guard, now cunning kikimoras have taken over. But Yasna, the daughter of the swamp lord, unexpectedly falls in love with Svetozar—the brave defender of the forest. Will their feelings be able to stop the years-long feud? Or will love fail under the weight of vengeance and the dark secrets that the swamp hides?
