Discover Trollheim: Kråkeslottets hemmelighet, the award-winning children's fantasy novel by Arne Lindmo. Learn about the plot, characters, and Norse mythology themes.

TROLLHEIM – Kråkeslottets hemmelighet is the first book in the popular Norwegian children's fantasy series Trollheim, written by Arne Lindmo and illustrated by Ida Skjelbakken. Released to critical acclaim, it won the prestigious ARKs barnebokpris in 2022, an award determined by a jury of over 10,000 children. The story blends modern realism with Norse mythology and horror elements, following three young friends who must battle ancient evils to save their world.

Plot Overview

The story is set in the small, eerie town of Trollheim, where local children speak in hushed tones about mysterious and frightening things lurking in the nearby woods. The narrative follows three protagonists—Adam, Tara, and Tobias—as they are thrust into the longest and most dangerous night of their lives.

To survive until dawn, the trio must uncover the secret of the "Crow Castle" (Kråkeslottet). Their journey forces them into a direct confrontation with an ancient evil that threatens not just their town, but the entire world. The book is designed for the "slukealder" (the age where children "devour" books), typically targeting readers between 8 and 13 years old.

Themes and Mythology

Trollheim: Kråkeslottets hemmelighet is noted for its integration of traditional Norwegian folklore and Norse mythology into a contemporary setting. Key mythological figures and themes mentioned throughout the series and its development include:

  • Norse Entities: The Midgard Serpent (Midgardsormen), Hel, and the Fenris Wolf (Fenrisulven).
  • Supernatural Creatures: Trolls, werewolves (varulv), and the "living dead" (levendedøde).
  • Atmosphere: The book balances action-heavy sequences with "shivering tension," horror (skrekk), and themes of friendship, warmth, and budding romance.

The publisher, Figenschou Forlag, describes the series as a modern equivalent to classic mystery series like The Hardy Boys (Hardyguttene) or Nancy Drew (Frøken Detektiv), aiming to capture the same sense of adventure for a new generation.

Visual Style and Illustrations

A defining feature of the book is the artwork by Ida Skjelbakken. Rather than traditional sketches, the book uses "photographic illustrations" that are specifically designed to complement the fantasy genre. These visuals help bridge the gap between a standard novel and a more immersive media experience, making the book accessible to "tweens" who may be transitioning to longer texts.

Kråkeslottets hemmelighet serves as the entry point into a larger saga. As of current publication records, the series includes:
