The Book of Koli
I've been having trouble going to sleep recently and had the suspicion that it might have to do with watching k-dramas on my laptop shortly before bedtime. In the hope that reading wouldn't have this effect, I downloaded The Book of Koli onto my Kindle and started that instead. With the result that I was still reading at 1am. It's great to have found a book I can't put down but it wasn't actually the effect I was aiming for! Possibly struggling with something in Swedish would have a more soporific effect. But anyway, The Book of Koli: right up my alley, so heartfelt thanks to the poster who recced it.
