I think I’ve only read two books by Icelandic authors.

Butterflies in November by Auður Ava Ólafsdóttir. Charming road-trip novel, I don’t remember much of the plot but I recall enjoying it. It has a section at the end with recipes for all the food mentioned throughout the story.

Snowblind by Ragnar Jónasson. Nordic noir/crime novel set in an isolated northern coast town. First in a series. Didn’t grab me, felt more shallow and less fleshed-out than some of the better works from this subgenre.

I admire anyone who translates novels from Icelandic into English, given how tricky Icelandic is, especially for non native speakers.
