My low-expectations principle was at fault from the outset : Niemi is a gifted storyteller, and the pitch is admirably atypical for Swedish literature - A giant tsunami-like flood wave rushes over northern Sweden, wreaking havoc. The key issue raised by Niemi is to what lengths we are prepared to go in order to survive.
It was an OK book, fairly well-written and thought-provoking. I just didn't find it quite as brilliant as I had expected to. I suppose I'm the one to blame, rather than Niemi, really.
