The "Finnish Weird" label that I've seen bandied around fits but also doesn't quite - it had me expecting a bit of a lighter quirkier book than this turned out to be. The first scene or two definitely feels like that, but it quickly becomes apparent that a more serious dystopia is being spun, along lines set out by the cover.

Actually I should praise the cover more: it's one of the best book covers I've ever seen, because it tells a lot of the story but without spoilers since none of it made sense until I had reached the relevant parts of the book.
