Assisted Living (aka Äldreomsorgen i Övre Kågedalen) by Nikanor Teratologen. It’s a very bleak and horrible story about a boy who is in an incestuous relationship with his nazi philosopher grandfather. Together the go around committing murder, rape, and other crimes, while relating everything to obscure authors and texts. The original is written entirely in a swedish dialect which is hard to understand, and it didn’t translate that well into other languages I think. Despite all this, it is very well written and has won prizes and been made into a play and radio reading etc.
