Note: The review below was taken directly from my Goodreads account.
The story itself is not as good as the blurb on the back leads you to believe. Despite reading another of Sjón's novels prior, I had an idea of what I'd be going into, but From the Mouth of the Whale was maybe weirder than The Blue Fox in terms of narrative structure. I almost wish this was set during Iceland's pagan times so that there would be a cool clash between monotheistic visitors and pagan Icelanders. I don't know what I'm saying anymore, except there were too many ellipses in parts I and IV but I think Nicolas Winding Refn could make a good movie out of it.
