I don't know how to review or rate this book since I understood very little of it. Based on other people's reviews, this book needs to be read several times in order for one to understand it. This is probably true. Now that I know what happens (which is not much), a second round would be easier. I'm just not interested in reading it again.

My enjoyment of this book was on and off. When I understood what was going on, I really enjoyed it. Most of the time I did not know who or what or when was being talked about. In this case, Finnish having only gender-neutral pronouns was probably making things worse since I had no clues into which character's POV we were in.

This is one of the first books in the genre of magical realism, inspiring Gabriel García Márquez, probably the most famous author of magical realism. I'm not in general such a big fan of magical realism - it's somehow just too convenient since nothing needs to be explained - but here it was quite interesting. 

Still, I can't in good faith give this more than 3 stars because it was utterly confusing, often on purpose for sure, and I didn't get much out of it. That could be because I am an unsophisticated pleb (but it might also be that everyone claims to love this book because that's what you should do to not look like an unsophisticated pleb).
It's a short book so if you're even a little bit interested, it's worth the try.
