Imagine a Norwegian Proust, albeit more concrete and with less repetition. The Amazon link is here, and you will notice that all nine Amazon reviews give it five stars. Here is a James Wood review from The New Yorker. Here is Wikipedia on the author. Here is a good blog review. Note this is only one out of six volumes, from Norway.
I would put this among the greatest Continental novels of the last fifty years and not at the bottom of that tier. It is not often that one discovers such books.
