After what both Titania and Stewart have said, I seriously consider picking The Ice Palace up as soon as possible--first, because they've made it sound almost irresistible, and second, because I love Scandinavian fiction (I only wish I had more time to read it, these days).
Vesaas seems keen to describe, in overflowing detail, the tender relationship existing between the two girls, which makes it sound (but only a little bit) like Peter Jackson's early film, Heavenly Creatures, which was based on a true story; also about a relationship between two young girls, Jackson made it a point to focus on the "magical" landscapes of their own devising--located somewhere within their united imaginations. Obviously, the movie is too different to be compared to Vesaas's book at length, but some thematic parallels might be spotted nonetheless.
I think The Ice Palace would be a perfect book for me since I'm a sucker for beautiful language and lush natural descriptions--
I told Titania once that Iceland was my dream-destination; right now I am seriously considering packing my bags and moving to Norway.
