Perhaps The Seducer by Jan Kjærstad. If I remember correctly, the main character is fairly non-typical of a Norwegian, and this is pointed out often through his actions.

Jo Nesbø is a very famous contemporary crime/thriller writer, with huge success abroad too. "Rødstrupe" or Redbreast, is my favourite of his. You'll gain some insight, I think.

Not personal favourites, but writers like Lars Saabye Christensen and Roy Jacobsen have written masterpieces about growing up in Norway in the 60s-70s.
