A novel by Anastasia Andrianova, author of the books “The Song of Monsters”, “The Way of the Magi” and “The Dead Kingdom”. With the arrival of night, the swamps are echoed with the howls of ghouls, and trouble is for those whom the darkness finds on the way. A year ago, swamp creatures dragged Mavna’s younger brother, Rasko, away, and her whole life changed: her mother fell ill, her older brother became unsociable and hot-tempered, and Mavna herself seemed frozen, having forgotten how to rejoice. One day a stranger appears in the village and gives Mavna a frog skin, and with it the hope that Rasko can still be saved. Mavna will have to step beyond the fence, into the frozen fog, and only the Patrons know who she will meet on this path. Step beyond the outskirts into the frightening unknown. Step into lands where nothing can protect you from ghouls. Mavna's younger brother, Rasko, perished in the swamps. A frog skin, given by a stranger, leads her there. Anxiety squeezes the heart, and only a spark of hope helps Mavna move forward. In the story, warm and cozy scenes contrast with dark and creepy ones. Fantasy, stitched with motifs of well-known Slavic fairy tales. An original interpretation of ghouls and the author's world! Will Mavna be able to find her brother and return home?
