Raspberry Hill is based on the Finnish- Swedish author Eva Frantz’s 2018 thriller for children and young people. The book won the 2019 Runeberg Junior Prize, where children themselves vote for the best book of the year. Raspberry Hill was a huge success, largely because it was – unconventionally – a scary story, and on account of the courageous way it tackled themes such as death, greed, evil and romance in an honest, non-adapted way.
