Deep in the freezing mountains lives a terrible, fearsome troll named Ulf. While most trolls are happy eating rocks or standard forest snacks, Ulf has a very specific, very nasty craving: he absolutely loves to chew on human fingers. He has terrorized the local villages for years, snatching up careless travelers and leaving them completely horrified. The adults are absolutely terrified of him, but a brave, sharp-witted young girl named Gudrun refuses to live in fear. She decides it is finally time to put an end to the troll's horrible habits once and for all. Armed with nothing but her intelligence and a very clever trick, Gudrun sets out to confront the beast head-on. Step into a thrilling, slightly spooky adventure where a courageous girl proves that brainpower will always defeat brute strength.
