I read this book in one go, it was impossible to put down. The illustrations made my jaw drop. They are amazing!

I would have loved this book as a 10 year old, and I love the book as an adult reader.

Author ARNE LINDMO was born in Norway in 1981. He worked for 10 years as a middle-grade teacher before he made his debut as an author. While teaching, he would think up a beginning and an end for a story every day that he could tell the students if there was time during the school day - and there often was! The children loved Arne's stories! So, as you understand, he knows his readers well, and now that he is a well-established, bestselling, and award-winning author in Norway, he travels around the country still meeting middle-grade students who now love his books.

Illustrator IDA SKJELBAKKEN was born in Norway in 1979. Her illustrations in the TROLLHEIM series have been very important for the fantastic reception and enormous success the books have achieved in Norway. The children say that they love her style. They think it's cool, realistic, and mature. Not visually childish like many of the other books they read, they say.
