Via friends in Spain I have discovered this interview with Swedish writer, Karin Tidbeck. If you are still wondering whether to buy a copy of Jagannath (which is one of the best-selling titles in my store right now) then perhaps reading the interview will help you make up your mind.
In the interview Karin talks, amongst other things, about why she has chosen to focus on creatures from Scandinavian folks tales, such as the vittra, rather than the much better known Norse gods. She also talks a bit about her debut novel, Amatka, which is currently only available in Swedish but will appear in English in due course.
